Hello, I am now trying to configure and build guix with the packages built by guix. So I installed autoconf, automake, binutils, glibc, gcc and ld- wrapper; added export GUIX_LD_WRAPPER_ALLOW_IMPURITIES=yes to my .bashrc as well as PATH, LIBRARY_PATH, CPATH, MANPATH and PKG_CONFIG_PATH. As discussed before, I also added export ACLOCAL="aclocal -I $HOME/.guix-profile/share/aclocal" . Now configure gives the error: checking for libgcrypt shared library name... libgcrypt checking for guile... (cached) /home/privat/.guix-profile/bin/guile checking for guile-config... /home/privat/.guix-profile/bin/guile-config checking for guile-tools... /home/privat/.guix-profile/bin/guile-tools checking whether libgcrypt can be dynamically loaded... no configure: error: GNU libgcrypt does not appear to be usable; see `--with- libgcrypt-prefix' and `README'. The file config.log ends with the following lines: configure:7038: checking for libgcrypt shared library name configure:7040: result: libgcrypt configure:7047: checking for guile configure:7077: result: /home/privat/.guix-profile/bin/guile configure:7091: checking for guile-config configure:7109: found /home/privat/.guix-profile/bin/guile-config configure:7121: result: /home/privat/.guix-profile/bin/guile-config configure:7135: checking for guile-tools configure:7153: found /home/privat/.guix-profile/bin/guile-tools configure:7165: result: /home/privat/.guix-profile/bin/guile-tools configure:7175: checking whether libgcrypt can be dynamically loaded configure:7190: result: no configure:7194: error: GNU libgcrypt does not appear to be usable; see `-- with-libgcrypt-prefix' and `README'. Do you see why and how to solve it? Andreas
