g++ custom dynamic library linking error undefined symbol
Ok, I’m looking for a solution for 2 days now. I didn’t find anything to solve my problems. What is currently going on? So, I tried creating a dynamic library (.so) on Linux Mint Maya 13 with g++. foolib.h: foolib.cpp: main.cpp: I compiled these files with these instructions: libfoo.so: foo: Creat…
Compiling and linking a 32 bit application on Debian 64 bit

Mach-O’s two-level namespace symbol resolution in ELF/linux

What is the difference between LD_LIBRARY_PATH and -L at link time?
I’m having problems with LD_LIBRARY_PATH at link time (this question has nothing to do with run time).

How do you link to a specific version of a shared library in GCC

I find that if I specify -lcurl it will link to libcurl.so.4 but Debian 4 systems only have libcurl.so.3 Is there some way I can tell …

I am attempting to link an application with g++ on this Debian lenny system. ld is complaining it cannot find specified libraries. The specific example here is ImageMagick, but I am having similar problems with a few other libraries too. I am calling the linker with: ld complains: However, libmagic exists: Ho…
