Top Forums Programming AIX linker oddities...what is going on? Post 302491065 by DreamWarrior on Wednesday 26th of January 2011 03:56:26 PM

Is there any way to force the compiler to behave like the Linux compiler? There are a few libraries we've had built for us that don't link all their dependencies correctly and, as such, we need to pull strings to get the linker to build the final executable "right" and in working order.... Sometimes we have to go searching around for the library that contains the symbol and link it to the main executable; sometimes that works (like pthreads took) and sometimes it doesn't (like curses didn't). I'd expect when linking mainsrc.c that if I tell the linker to link a library that it will regardless of whether or not code in that library is needed.

So, while you may very well be correct about libm, that doesn't explain pthreads vs. curses. I don't have to use any functions from pthreads to force the linker to give main a dependency to that, while I do have to use a function from curses to get that dependency. What gives there?

g-wrap-config(1)					      General Commands Manual						  g-wrap-config(1)

NAME
g-wrap-config - script to get information about the installed version of G-Wrap SYNOPSIS
g-wrap-config [ --version ] [ --c-compile-args LANG | --c-link-args LANG | --guile-module-directory ] DESCRIPTION
g-wrap-config is a tool that is used to configure and determine the compiler and linker flags that should be used to compile and link progams, libraries, and plugins that use G-Wrap. However, since G-Wrap 1.9, this tool has been deprecated in favor of pkg-config(1). New code should use the g-wrap-2.0-guile pkg-config module, g-wrap-config only exists for compatibility reasons. OPTIONS
--c-compile-args LANG Print the compiler flags that are necessary to compile a program or library that uses the G-Wrap language binding for LANG. --c-link-args LANG Print the linker flags that are necessary to link a program that uses the G-Wrap language binding for LANG. --version Prints the currently installed version of G-Wrap on standard output. EXAMPLES
gcc -o main.o $(g-wrap-config --c-compile-args guile) main.c is how you might use g-wrap-config to compile a C source file for an executable program. gcc -o my_app $(g-wrap-config --c-link-args guile) main.o util.o is how you might use g-wrap-config to link compiled objects into an executable program.
