libpng: le compilateur C ne peut pas créer d'exécutable
J'essaie d'appeler la commande ./configure. Mais, cela montre cette erreur:
C compiler cannot create executables.
Voici la sortie:
checking for a BSD-compatible install... /home/linuxbrew/.linuxbrew/bin/ginstall -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /home/linuxbrew/.linuxbrew/bin/mkdir -p
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking whether make supports nested variables... yes
checking whether to enable maintainer-specific portions of Makefiles... no
checking for gcc... gcc
checking whether the C compiler works... no
configure: error: C compiler cannot create executables
See `config.log' for more details
J'ai vérifié le config.log, il peut détecter le fichier gcc installé mais il ne trouve pas le fichier conftest.c. J'ai déjà essayé:
Sudo apt-get update
Sudo apt-get install build-essential
Mais cela montre toujours l'erreur. J'ai également vérifié que mon libc6 est déjà installé dans la version la plus récente.
Comment le résoudre?
C'est le config.log:
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.
It was created by libpng configure 1.6.32, which was
generated by GNU Autoconf 2.69. Invocation command line was
$ ./configure

Comme nous pouvons le constater dans le fichier config.log, gcc est appelé avec un argument supplémentaire /media/Data/Libs qu'il interprète comme un fichier de bibliothèque qu'il doit tenter de lier:
configure:3333: gcc conftest.c /media/Data/Libs >&5
/usr/bin/ld: cannot find /media/Data/Libs: File format not recognized
En regardant plus loin, nous pouvons voir que cela est récupéré de votre environnement via le fichier ac_cv_env_LIBS_value de autoconf:
ac_cv_env_LDFLAGS_set=
ac_cv_env_LDFLAGS_value=
ac_cv_env_LIBS_set=set
ac_cv_env_LIBS_value=/media/Data/Libs
ac_cv_env_LT_SYS_LIBRARY_PATH_set=
ac_cv_env_LT_SYS_LIBRARY_PATH_value=
Cela suggère que vous avez défini une variable d'environnement LIBS=/media/Data/Libs et que /media/Data/Libs est probablement un répertoire, son format n'est pas reconnu en tant que fichier de bibliothèque par ld.
Il est probable que LIBS=/media/Data/Libs ne soit pas lié à la construction de ce logiciel et LIBS est simplement un nom que vous avez utilisé pour une variable dans un autre contexte. C'est un bon rappel pour éviter les noms en majuscules pour de telles variables.
Pour l'instant, vous pouvez simplement exécuter unset LIBS dans le shell, puis réexécuter ./configure
