g++ fails to link to static library when compilation and link in single command
Hello All,
I've encountered a strange behaviour from g++ that doesn't make sense to me. Maybe you can shed some light on it:
I have a bunch of source files and want to compile them and link them with a static library liba.a located in /usr/local/lib64 into an executable
Approach 1 works fine:
Approach 2 doesn't work:
That causes a load of undefined references, It's a shame, because method 2 is what my makefile produces.
Can anyone tell me the difference between 1 and 2 and how to fix it?
Hello,
J have a problem when I use gcc:
This comand works:
gcc -shared -fpic -I/usr/include/sys -I/usr/include -L/usr/lib/librt.sl essai1.c mylib.sl
but
gcc I/usr/include/sys -I/usr/include -L/usr/lib/librt.sl essai2.c -o essai
don't work.

Is it possible to link a library compiled on Solaris 10 with SunCompiler 5.9 in a project compiled with SC 5.8 ?
Is there an option to "downgrade" the SC5.9 => SC5.8 to be sure of the compatibility ?
Thanks 4 your help (2 Replies)

FORT77(1) Linux Programmer's Manual FORT77(1)NAME
fort77 - invoke f2c Fortran translator transparently, like a compiler
SYNOPSIS
fort77 [-c] [-g] [-v] [-k] [-P] [-cpp] [f2c option ...] [-L directory ...] [gcc-option ...] [link option ...] [-O optlevel] [-o out-
file] [-s] [-w] [-Wx,arg1[,arg2]...] file ...
DESCRIPTION
The fort77 script invokes the f2c command transparently, so it can be used like a real Fortran compiler. It can be used to compile For-
tran, C and assembler code, and to link it with the f2c libraries.
File arguments ending with .f are compiled as Fortran source files. Files which end with .P are passed through to f2c, and files ending
with .F are passed to the C preprocessor (invoked as "/lib/cpp -traditional") first. Any switches passed via -D will be passed to the pre-
processor. If the translation is successful, the resulting C files will be passed to cc for translation into an object file. Files ending
in .c, .C, .cc, .i, .s, .S, .m, .cc or .cxx are passed to the GNU C compiler directly; see gcc(1). All other files are passed to the
linker.
OPTIONS -c Supress linking and produce an object ( .o ) file from each source file.
-g Include debugging information. -v Be verbose; supplying this twice will also tell the C compilers etc to be verbose.
-k Keep the C files generated by f2c around.
-cpp Pass Fortran code through the C preprocessor, as if filenames ended in .F.
-P Generate f2c .P files.
-Ldirectory
Include directory in the search for libraries in the final linking stage.
-o outfile
Send output to outfile.
-trapuv Have f2c generate code to trap uninitialized values.
-Wx,arg1[,arg2...]
Pass the argument[s] argi through to the subprocess x, where x can assume one of the following values: f for the f2c step, p for
the preprocessing step, c for the C compiler, a for the assembler (this is actually passed to the C compiler, too), and l for the
linker. As an example, defining a preprocessor constant for the C compilation step would be done with -Wc,-DUNIX=1. Specifying
the -f option to f2c would be done via -Wf,-f.
f2c option
fort77 passes through almost all f2c options: -C, -U, -u, -a, -E, -h, -P, -R, -r, -z, -I2, -I4, -onetrip, -!c, -!l, -!P, -!R, -ext,
-!bs, -W[n], -trapuv, -w8, -r8 and -w66.
gcc options
The following options are passed through to gcc: -f*, -W*, -U*, -A*, -m*, -S, -E, -v, -x, -pipe, -o, -I, -V, -b*, -p, -pg.
linker option
The options passed to the linking stage are -static, -shared, -v, -V, and -symbolic.
BUGS
To make debugging work, you need to set a breakpoint at MAIN__ before you start.
f2c This script automatically supplies the -I. option to f2c. Older versions of f2c may not support this.
This script is for the interaction of gcc and f2c; using it with another compiler will probably require modification.
The fort77 script does not strictly conform to Posix.2, because it acceppts long options with one leading slash. This is done for gcc com-
patibility.
