Dear Erik: I have carefully read through config.log file, and I found out some possible problems for compilation failure, could you please help me to locate the real reason and solution?
As I think, maybe this error is from xlc, but it seemed much related to "conftest.c" file, which was reported for several times as errors. How should I deal it with? By the way, I have passed through the compilation of single version. The following errors were from MPI compilation. Of course, I only added a "--enable-mpi" flag when compling MPI version, as described in the last email. config.log: ... ... ... ## ----------- ## ## Core tests. ## ## ----------- ## ... ... configure:2586: checking for C compiler version configure:2589: xlc --version </dev/null >&5 xlc: 1501-216 command option --version is not recognized - passed to ld ... ... ... configure:2806: checking whether we are using the GNU C compiler configure:2830: xlc -c -O3 -qarch=pwr4 -qtune=pwr4 -qansialias -w -I/afs/ipp-garching.mpg.de/home/x/xieyh/fftw_213/include conftest.c >&5 "conftest.c", line 20.14: 1506-275 (S) Unexpected text me encountered.
