Hi, all. I've asked this question on the GMP mailing list, but there were no replies at all. I'm building GCCs on the Ci20 Creator dev board, which is a dual-core MIPS32 platform. GCC 5.4.0 finished building overnight but make check failed in libgmp. The failure mode though is rather strange. Get this; /bin/bash: line 8: ./t-jac: Permission denied FAIL: t-jac /bin/bash: line 8: ./t-bin: Permission denied FAIL: t-bin /bin/bash: line 8: ./t-get_d: Permission denied FAIL: t-get_d /bin/bash: line 8: ./t-get_d_2exp: Permission denied FAIL: t-get_d_2exp /bin/bash: line 8: ./t-get_si: Permission denied FAIL: t-get_si /bin/bash: line 8: ./t-set_d: Permission denied FAIL: t-set_d /bin/bash: line 8: ./t-set_si: Permission denied FAIL: t-set_si /bin/bash: line 8: ./t-fac_ui: Permission denied FAIL: t-fac_ui /bin/bash: line 8: ./t-fib_ui: Permission denied FAIL: t-fib_ui /bin/bash: line 8: ./t-lucnum_ui: Permission denied FAIL: t-lucnum_ui /bin/bash: line 8: ./t-scan: Permission denied FAIL: t-scan And indeed, those binaries although they exist, do not have their execute bits set. ci20@ci20:~/tmp/gcc$ find . -name t-get_d ./gmp/tests/mpn/t-get_d ./gmp/tests/mpz/t-get_d ci20@ci20:~/tmp/gcc$ ls -l ./gmp/tests/mpz/t-get_d -rw-r--r-- 1 ci20 ci20 558980 Apr 21 07:57 ./gmp/tests/mpz/t-get_d ci20@ci20:~/tmp/gcc$ ls -l ./gmp/tests/mpn/t-get_d -rwxr-xr-x 1 ci20 ci20 716340 Apr 21 07:55 ./gmp/tests/mpn/t-get_d The "mpn" version of the test earlier was called, and passed. Any ideas? I've googled of course, but nothing even remotely similar came up.
