Jelle, thank you for your suggestion But there's something I don't understand the suggestion to add --with-freexl-prefix=$GUIX_ENVIRONMENT fixes my guile-freexl but is nor necessary in guile-gcrypt why ? 2017-06-03 22:49 GMT+02:00 Jelle Licht : > > Catonano writes: > > > checking for libfreexl-config... no > > checking libfreexl's library directory... > > checking for libfreexl shared library name... libfreexl > > checking whether libfreexl can be dynamically loaded... no > > configure: error: GNU libfreexl does not appear to be usable; see > > `--with-libfreexl-prefix' and `README'. > > > The following command seemed to run to completion for me: > [env]$ ./configure --with-freexl-prefix=$GUIX_ENVIRONMENT > > Maybe check out the following link, by coincidence about gcrypt as well > ;-). > https://lists.gnu.org/archive/html/bug-guix/2013-02/msg00062.html > > this is an excerpt from running configure in guile-gcrypt checking for guile-config... /home/catonano/.guix-profile/bin/guile-config checking for libgcrypt-config... /gnu/store/1y54p19lvz3rh6a5dyynnffn9dbal2li-profile/bin/libgcrypt-config checking libgcrypt's library directory... /gnu/store/hag795ji8p9vqikwp8cibfibpsa39s3n-libgcrypt-1.7.6/lib checking for libgcrypt shared library name... /gnu/store/hag795ji8p9vqikwp8cibfibpsa39s3n-libgcrypt-1.7.6/lib/libgcrypt As you can see it checks that "...bin/libgcrypt-config" is present AND it checks the "shared library name" Now this is configure from my guile-freexl checking for guile-config... /home/catonano/.guix-profile/bin/guile-config checking for freexl shared library name... /gnu/store/13p9jpf8gp3mg414az1dsf59vw2hyyw2-profile/lib/libfreexl as you can see it DOESN'T look for any ...bin/freexl-config AND it doesn't look for the library shared name why ? It is substantially the same repo, I cloned it and changed the strings "gcrypt" to "freexl" That's all I did
