Maybe there is a mistake on the previous reply, GLPK is 32/64 bits depending on the compilation/platform/OS on 64 bits operating systems it can allocated more than 4GB of memory.

Can you use gdb to see how much memory was attempted to allocate ?

Hey Community!
Just ran into the following problem glp_alloc: no memory available
Error detected in file ..\src\env\alloc.c at line 91
We've got plenty of memory (both RAM and hard drive). Any tips?
GLPK is a 32-bit software, so the addressing memory is limited to 4 Gb.


Best,
