UNIX for Dummies Questions & Answers

Hi all!

I'm working on a HP UX 11 machine. I have an executable build with gcc and a shared library (sl) build with aCC. If i start the executable, i have many errors about unresolved symbols. Is the binary output of aCC and gcc compatible?

Greetings!

I have never tried that. But I would be astonished if it worked. gcc is not even source level compatible with aCC. There is a lot of code out there marked "gcc only".

Why would you build a library with one compiler and an executable with another? Why not try a single compiler?

I have tried that! I need to get AXIS C++ to run.

AXIS uses the xercesc library which cannot be compiled with g++ on my machine. The makefile contains an error with the compiler flags, it seems that the 'configure' script think i'm using the aCC compiler.

AXIS itself cannot be compiled with aCC, only with g++.

Im getting nuts with that....

I don't know what AXIS is. If it needs g++, it's not written in C++. A C++ program can be compiled by any C++ compiler including aCC (which is actually my favorite compiler). The gcc folks have invented their own language.

Since you must use g++ to compile AXIS, you need to go with that. You lost me with this makefile/configure script stuff. But you should be able to control configure to use gcc. Or you should be able to edit the makefile to do so. If nothing else, rename aCC while configure is running.

You cannot use a shared library build with aCC with an
executable built with gcc.

xercesc compiles fine on HP-UX with gcc. You just need to
configure the build correctly. Make use that you have a
version of gcc that builds HP-UX shared libraries correctly.

I've update the following develop tools:

automake 1.7.4
flex 2.5.4a
gcc 3.3.2
libtool 1.5
m4 1.4
make 3.80
latest linker 'ld' patch for hpux

i've configured the build with:
runConfigure -php-11 -cgcc -xg++

and this is the error i would get:

g++ -D_HP_UX -DXERCES_TMPLSINC -DHPUX11 +DAportable +eh +Z -Z +a1 +d -ptr/obj/HPUX/ptrepository -c -I/include -g -O2 -o /obj/HPUX/GCCDefs.o GCCDefs.cpp
g++: cannot specify -o with -c or -S and multiple compilations

I dont think i have making something wrong...


Thank you!
Greeting

Well somebody did something wrong.

What is -ptr/obj/HPUX/ptrepository supposed to mean?

I don't have -Z or +Z on my gcc man page, but it's hard to believe that you might want them both.

Sometimes freeware crashes and burns.
