Simply pass -Wl,–exclude-libs,ALL to gcc This will tell the linker to transform all the symbols in the static libraries to hidden. –exclude-libs also accepts a list of archives (i.e. static library names) for finer granularity on which libraries to hide symbols from. Note: this will only work in systems using GNU binutils (e.g. Linux) or … Read more
Passing -relocatable or -r to ld will create an object that is suitable as input of ld. $ ld -relocatable a.o b.o -o c.o $ gcc c.o other.o -o executable $ ./executable The generated file is of the same type as the original .o files. $ file a.o a.o: ELF 32-bit LSB relocatable, Intel 80386, … Read more
Static libraries have special rules when it comes to linking. An object from the static library will only be added to the binary if the object provides an unresolved symbol. On Linux, you can change that behavior with the –whole-archive linker option: g++ -Wl,–whole-archive some_static_lib.a -Wl,–no-whole-archive
Statically linking against any system library, and especially against libc, on modern UNIX or Linux systems makes the binary significantly less portable. Just don’t do it. Instead, use backward compatibility (binaries linked on an older system continue to run on all newer ones) to your advantage, either by linking your binary on an old system … Read more
As already pointed out, nvcc depends on gcc 4.4. It is possible to configure nvcc to use the correct version of gcc without passing any compiler parameters by adding softlinks to the bin directory created with the nvcc install. The default cuda binary directory (the installation default) is /usr/local/cuda/bin, adding a softlink to the correct … Read more
To invoke a dry run: make -n This will show what make is attempting to do.
You may try to include library headers using -isystem instead of -I. This will make them “system headers” and GCC won’t report warnings for them.
The -Wl,xxx option for gcc passes a comma-separated list of tokens as a space-separated list of arguments to the linker. So gcc -Wl,aaa,bbb,ccc eventually becomes a linker call ld aaa bbb ccc In your case, you want to say “ld -rpath .“, so you pass this to gcc as -Wl,-rpath,. Alternatively, you can specify repeat … Read more
It is for resolving circular dependences between several libraries (listed between -( and -)). Citing Why does the order in which libraries are linked sometimes cause errors in GCC? or man ld http://linux.die.net/man/1/ld -( archives -) or –start-group archives –end-group The archives should be a list of archive files. They may be either explicit file … Read more
