Your message would be more appropriate for the john-users list than for john-dev. You're reporting a problem rather than intend to participate in JtR development (as far as I can tell from your message). > make clean && make [...] > make: Entering directory > `/nfs__share/ae/cc/189/JohnTheRipper/src/escrypt' > /bin/rm -f tests crypto_scrypt-best.o crypto_scrypt-common.o sha256.o > tests.o crypto_scrypt-*.o > make: Leaving directory `/nfs__share/ae/cc/189/JohnTheRipper/src/escrypt' > make find_version > make: Entering directory `/nfs__share/ae/cc/189/JohnTheRipper/src' > /bin/mkdir -p ../run/kernels > cp ../run/kernels ../run/kernels > cp: omitting directory `../run/kernels' > make: *** [opencl/7z_kernel.cl] Error 1 I can't reproduce the problem. For me, this looks as follows: make: Entering directory `/home/solar/j/bleeding-jumbo-20171026/src/escrypt' /bin/rm -f tests crypto_scrypt-best.o crypto_scrypt-common.o sha256.o tests.o crypto_scrypt-*.o make: Leaving directory `/home/solar/j/bleeding-jumbo-20171026/src/escrypt' make find_version make: Entering directory `/home/solar/j/bleeding-jumbo-20171026/src' /bin/mkdir -p ../run/kernels cp opencl_device_info.h ../run/kernels cp opencl_misc.h ../run/kernels ... and so on. In your case, the "cp ../run/kernels ../run/kernels" command is clearly wrong, but it is unclear why it became so wrong. magnum, on a related note, maybe we should have configure suggest "-j" in the second make, e.g. replace: Configure finished. Now 'make clean && make -s' to compile. with: Configure finished. Now 'make clean && make -sj8' to compile. given that almost everyone is on a multi-core machine these days. Ideally, we'd determine and include the logical CPU count in there, but even a generally reasonable constant like 8 would do. Alexander
