Change stack size for a C++ application in Linux during compilation with GNU compiler

Question

In OSX during C++ program compilation with g++ I use

LD_FLAGS= -Wl,-stack_size,0x100000000
         


        

Answer 1

Instead of stack_size, use --stack like so:

gcc -Wl,--stack,4194304 -o program program.c

This example should give you 4 MB of stack space. Works on MinGW's GCC, but as the manpage says, "This option is specific to the i386 PE targeted port of the linker" (i.e. only works for outputting Windows binaries). Seems like there isn't an option for ELF binaries.
