Hello * and a happy new year, As regards $subject, this so-called STRING_ENCODING_CHARMAP may be relevant: https://github.com/hpcugent/easybuild-framework/blob/master/easybuild/tools/filetools.py#L59 Look around line L1000 for the rational of that design and some pointers. Basically, ` ` becomes `_space_` and so on, for many more potentially tricky characters. The aim was to have freedom in relation to packages/filenames. It seems to work OK!

(*) To make a long story short, we faced the same problem during EasyBuild open source project, for building software intended for HPC platforms; in fact, that one issue triggered me to request EB’s first hackathon whereby, in the issued Pull Request, I contained the wishes of a handful of people. It is not known if there are better ways to go about it - and if so, what’s that? We opted for that solution as the least hackish or, least worst. It does not preserve 1-1 character mapping but IMHO no generic solution would do that, anyhow. I hope you find this technique useful/relevant. enjoy, Fotis ps. If you know *anybody* who has setup a database of build modes/instructions for 1000s of software packages across architectures & OS platforms, kindly pass on the information! (ie. something more reusable than pkgsrc) N.B. autoconf build processes are handled out-of-the-box by EB, here is an example: https://github.com/hpcugent/easybuild-easyconfigs/blob/master/easybuild/easyconfigs/a/ABySS/ABySS-1.3.6-goolf-1.4.10-Python-2.7.5.eb If you wonder why we bother with yet another build system, obviously, you haven’t been debugging HPC environments for 100s of users; have fun reading this: https://github.com/hpcugent/easybuild-easyblocks/blob/master/easybuild/easyblocks/b/boost.py -- echo "sysadmin know better bash than english" | sed s/min/mins/ \ | sed 's/better bash/bash better/' # signal detected in a CERN forum _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
