Hi I am trying to create a new easyconfig for the application USEARCH, where a licence condition of the free version is that the permissions of the installed executable be changed to 0111, to discourage copying. I cannot get this permissions change to work. Here is my easyconfig:
easyblock = 'Binary' name = 'USEARCH' version = '11.0.667' versionsuffix = '_i86linux32' homepage = 'https://www.drive5.com/usearch/index.html' description = """ USEARCH is a unique sequence analysis tool with thousands of users world-wide. USEARCH offers search and clustering algorithms that are often orders of magnitude faster than BLAST. """ toolchain = SYSTEM _download_file = 'usearch%(version)s%(versionsuffix)s' _installed_file = '%(installdir)s/%(namelower)s' # Download via form at # https://www.drive5.com/usearch/download_academic_site.html sources = [_download_file] checksums = ['492c4dafedcf6acf99782357a7ca32c26e7bd395fc9867c2ac3b26fbbd4cd501'] #install_cmd = 'mv %s %s && ' % (_download_file, _installed_file) #install_cmd += 'chmod 111 %s' % _installed_file # Licence condition. postinstallcmds = [ 'mv %s %s' % (_download_file, _installed_file), 'chmod 111 %s' % _installed_file # Licence condition. ] modloadmsg = """This is the free-of-charge 32-bit version of USEARCH.""" sanity_check_paths = { 'files': ['%(namelower)s'], 'dirs': [], } sanity_check_commands = ['usearch --version'] moduleclass = 'bio' I have tried this with both "install_cmd" uncommented in the file and "postinstallcmds" commented out; and vice versa (as above). In neither case does the "chmod" command seem to do anything. The log file shows it as having been run, and as having an exit code of 0. An additional but less important problem with the "postinstallcmds" version is that it leaves the original downloaded filename in place, alongside the copy with the new name (which is plain 'usearch'), as though it has run "cp" instead of "mv". I do not get this problem when I use "install_cmd" in the easyconfig. Does anyone have any idea what is going wrong here? Perhaps I should be using a different easyblock - but which?
