I'm trying to build the ppl and cloog requires for building gcc, and have found that both ppl 0.11 and 0.12.1 builds crash because of a boatload of errors in the ppl_lpsol demo. The errors look like this. These are from ppl-0.12.1 and there are many more errors.

ppl_lpsol.c:583: error: implicit declaration of function ‘lpx_set_int_parm’ ppl_lpsol.c:583: error: ‘glpk_lp’ undeclared (first use in this function) ppl_lpsol.c:583: error: (Each undeclared identifier is reported only once ppl_lpsol.c:583: error: for each function it appears in.) ppl_lpsol.c:583: error: ‘LPX_K_MSGLEV’ undeclared (first use in this function) ppl_lpsol.c:585: error: ‘LPX_LP’ undeclared (first use in this function) ppl_lpsol.c:588: error: implicit declaration of function ‘lpx_set_obj_dir’

PPL 0.11 and PPL 0.12.1 are very old releases. Apparently you are using a newer version of GNU GLPK, which has a different and incompatible API. Both PPL 0.11 and PPL 0.12.1 were tested with versions of of GLPK that were current at the time of release.

Why did you release software packages with these easily discoverable defects? I wasted several hours this morning compiling and got nothing.

You are not saying this seriously, are you?

You can:

1) disable ppl_lpsol if you (as I guess) do not need it: read the file README.configure for details;

2) downgrade GNU GLPK to a version that was current when the version of the PPL you want to use was released;

3) upgrade PPL: we recommend the latest release, PPL 1.1.

OS: Debian Linux 6.0.9 compilers: GCC-4.4.5 GCC and G++
