How to compile a software for a non-typical platform?
I am quite new to compiling source codes in linux and have been running into a lot of problems in trying to do so since the platform configuration is different from most.
For starters, I know that you need to enter the following commands in order to install any software manually in linux:
Code:
./configure
make
make install
But I was never able to run all these three commands successfully. For a current problem of installing jabberd2, I run into ./configure problem of not being unable to find Libidn:
Code:
checking for Libidn version >= 0.3.0... no
configure: error: Libidn >= 0.3.0 not found
I verified via ipkg command that I do have Libidn version 1.25-1. I think it should be installed in either in /opt/bin or /opt/sbin. I looked through the help options in configure:
Code:
`configure' configures jabberd 2.3.4 to adapt to many kinds of systems.
Usage: ./configure [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print `checking ...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for `--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or `..']
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[/usr/local]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc. You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]
--localedir=DIR locale-dependent data [DATAROOTDIR/locale]
--mandir=DIR man documentation [DATAROOTDIR/man]
--docdir=DIR documentation root [DATAROOTDIR/doc/jabberd]
--htmldir=DIR html documentation [DOCDIR]
--dvidir=DIR dvi documentation [DOCDIR]
--pdfdir=DIR pdf documentation [DOCDIR]
--psdir=DIR ps documentation [DOCDIR]
Program names:
--program-prefix=PREFIX prepend PREFIX to installed program names
--program-suffix=SUFFIX append SUFFIX to installed program names
--program-transform-name=PROGRAM run sed PROGRAM on installed program names
System types:
--build=BUILD configure for building on BUILD [guessed]
--host=HOST cross-compile to build programs to run on HOST [BUILD]
Optional Features:
--disable-option-checking ignore unrecognized --enable/--with options
--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)

--enable-silent-rules less verbose build output (undo: "make V=1")
--disable-silent-rules verbose build output (undo: "make V=0")
--enable-dependency-tracking
do not reject slow dependency extractors
--disable-dependency-tracking
speeds up one-time build
--enable-static[=PKGS] build static libraries [default=no]
--enable-shared[=PKGS] build shared libraries [default=yes]
--enable-fast-install[=PKGS]
optimize for fast installation [default=yes]
--disable-libtool-lock avoid locking (might break parallel builds)
--enable-developer Compile with warnings and debugging symbols
--enable-debug enable debug messages
--enable-nad-debug enable NAD pointer tracking

--enable-pgsql=DIR enable PostgreSQL auth/reg/storage support (no)
--enable-sqlite enable SQLite3 auth/reg/storage support (no)
--enable-db enable Berkeley DB auth/reg/storage support (no)
--enable-oracle enable Oracle auth/reg/storage support (no)
--enable-ldap enable OpenLDAP auth/reg support (no)
--enable-pam enable PAM auth/reg support (no)
--enable-pipe enable pipe auth/reg support (no)
--enable-anon enable anonymous auth/reg support (no)
--enable-fs enable filesystem storage support (no)
--enable-websocket enable WebSocket support on C2S port (no)
--enable-mio=BACKENDS use one of BACKENDS to drive MIO (select poll epoll
kqueue)
--enable-superseded enable superseded XEP support (yes)
--enable-experimental enable experimental features (yes)
--enable-tests enable tests (yes)
--enable-werror Treat all warnings as error
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-pic[=PKGS] try to use only PIC/non-PIC objects [default=use
both]
--with-gnu-ld assume the C compiler uses GNU ld [default=no]
--with-sysroot=DIR Search for dependent libraries within DIR
(or the compiler's sysroot if not specified).
--with-extra-include-path
use additional include paths
--with-extra-library-path
use additional library paths (remember to update
/etc/ld.so.conf too)
--with-zlib=DIR search for zlib in DIR
--without-zlib disable use of zlib
--with-oracle-home=DIR the Oracle home directory, for includes and libs
--without-subst disable use of substitution library
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
LIBS libraries to pass to the linker, e.g. -l<library>
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
you have headers in a nonstandard directory <include dir>
CPP C preprocessor
PKG_CONFIG path to pkg-config utility
PKG_CONFIG_PATH
directories to add to pkg-config's search path
PKG_CONFIG_LIBDIR
path overriding pkg-config's built-in search path
CHECK_CFLAGS
C compiler flags for CHECK, overriding pkg-config
CHECK_LIBS linker flags for CHECK, overriding pkg-config
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
Since I am not sure what I am doing is correct or not, I found that none of the following commands work:
The software you're trying to build needs Libidn version >= 0.3.0 which presumably means a version 0.x.y where x >= 3 and y >= 0. A change in value in the 1st number in the version (0 to 1 in this case) indicates incompatible changes to the interfaces in the library that the code you're building is not prepared to handle.
You need to either get a newer version of the software you're building (that wants a Libidn version 1.x.y with x <= 25 or install an additional version of Libidn with version 0.x.y where x >= 3.
Note also that libraries should be loaded into a directory with a final component being lib; not bin.
You need to either get a newer version of the software you're building (that wants a Libidn version 1.x.y with x <= 25 or install an additional version of Libidn with version 0.x.y where x >= 3
None of the two choices is an option since the older version of Libidn (0.x) is not available for download and I am using the newest version of the software.
Fortunately, I was able to install alternative software using a different method that can substitute for it. But going back to the ./configure problem...if I enter the following command:
Code:
./configure --prefix=/opt
Doesn't that mean PREFIX is set to /opt? Then there won't be a need to set the following:
Code:
--includedir=/opt/include
Since includedir is PREFIX/include, which should yield /opt/include.
The strange part is when I enter a make command. I stumble upon a problem of unable to find a header file even through it is at /opt/include. What am I doing wrong?
Input file
I have a file with four fields.
f1,f2,f3,f4
A,1,10,00,S
B,2,20,00,00,D
C,3,100,00,00,G
I want Output like
f1|f2|f3|f4
A|1|10,00|S
B|2|20,00,00|D
C|3|100,00,00|G
please help on this (4 Replies)
Hi Experts,
In a particular dir, I have many files *AJAY*.
How can I get total size of all such files.
I tried du -hs *AJAY* but it gave me individual size of all files.
All I require is summation of all.
Thanks,

Hi All,
I need to store the output of "find ." to an array one by one. Output of find . in my case will look like :-
.
./one
./one/a
./one/b
./one/c
./two
So my first array element should be "/one" and second one "/one/a" (need to remove "." from the output as well).
Then I need to... (11 Replies)
