I'm trying to get gmp working with Dev-cpp on Windows 8.1. I've got msys set up and trying to build gmp, with no success. First, I got M4 errors, which I managed to fix, but now I'm stuck for a few hours and the internet isn't helping much. These are the warnings and errors I get:
configure: WARNING: +---------------------------------------------------------- configure: WARNING: | Cannot determine global symbol prefix. configure: WARNING: | /c/Program Files (x86)/Dev-Cpp/MinGW64/bin/nm output doesn't contain a global data symbol. configure: WARNING: | Will proceed with no underscore. configure: WARNING: | If this is wrong then you'll get link errors referring configure: WARNING: | to ___gmpn_add_n (note three underscores). configure: WARNING: | In this case do a fresh build with an override, configure: WARNING: | ./configure gmp_cv_asm_underscore=yes configure: WARNING: +---------------------------------------------------------- checking how to switch to read-only data section... .section .rdata,"dr" checking for assembler .type directive... checking for assembler .size directive... checking for assembler local label prefix... configure: WARNING: "/c/Program Files (x86)/Dev-Cpp/MinGW64/bin/nm" failure configure: WARNING: cannot determine local label, using default L L checking for assembler byte directive... .byte checking how to define a 32-bit word... ./configure: line 25284: /c/Program: No such file or directory ./configure: line 25284: /c/Program: No such file or directory configure: error: cannot determine how to define a 32-bit word configure: WARNING: cache variable lt_cv_path_LD contains a newline
I'd be really grateful for any help given.
Let's look at the errors:
checking for assembler local label prefix... configure: WARNING: "/c/Program Files (x86)/Dev-Cpp/MinGW64/bin/nm" failure configure: WARNING: cannot determine local label, using default L L checking for assembler byte directive... .byte checking how to define a 32-bit word... ./configure: line 25284: /c/Program: No such file or directory ./configure: line 25284: /c/Program: No such file or directory
Specifically /c/Program: No such file or directory. That seems to indicate that configure is not happy with the fact that Mingw is installed to a path that contains a space. So my guess is that the cleanest way forward is to find a way for your compiler to be installed to a path that contains no spaces.
