Curiosity drove me to give it a look. From what I understand: libgit2 seems to be multiplatform and for some of the platforms (this time Windows) they are shipping files with the same names that those that we can find in /usr/include, in this case inttypes.h. You have include in your patch to use the system version of libgit2 an -I/usr/include/git2 which is making the compilation to use the inttypes.h from libgit2 (the windows copy) instead of the one in /usr/include (which is evaluated the last by the compiler).
Something like this patch should work, although I did not test it: """ diff --git a/debian/patches/use_debian_packaged_libgit2.patch b/debian/patches/use_debian_packaged_libgit2.patch index ab603cd..c716773 100644 --- a/debian/patches/use_debian_packaged_libgit2.patch +++ b/debian/patches/use_debian_packaged_libgit2.patch @@ -87,7 +87,7 @@ Last-Update: Wed, 10 Jan 2018 10:33:31 +0100 if test "x${have_ssh2}" = xyes; then - LIBSSH2_CFLAGS="-Ilibgit2/deps/libssh2/include" - LIBSSH2_LIBS="-Llibgit2/deps/libssh2/lib -lssh2" -+ LIBSSH2_CFLAGS="-idirafter /usr/include/git2" ++ LIBSSH2_CFLAGS="-I/usr/include/git2" + LIBSSH2_LIBS="-lgit2 -lssh2" fi fi @@ -97,7 +97,7 @@ Last-Update: Wed, 10 Jan 2018 10:33:31 +0100 # Add include paths for git2r -CPPFLAGS="-I. -Ilibgit2/src -Ilibgit2/include -Ilibgit2/deps/http-parser ${CPPFLAGS}" -+CPPFLAGS="-I. -idirafter /usr/include/git2 ${CPPFLAGS}" ++CPPFLAGS="-I. -I/usr/include/git2 ${CPPFLAGS}" # Add definitions CPPFLAGS="${CPPFLAGS} -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -DGIT_OPENSSL -DLIBGIT2_NO_FEATURES_H" """ If use the "-idirafter" option the libgit2 headers are evaluated in the last position when invoking the compiler, so the linux system inttypes.h go first: https://gcc.gnu.org/onlinedocs/cpp/Invocation.html#Invocation On Thu, Jan 11, 2018 at 12:15 AM, Philip Rinn <ri...@inventati.org> wrote: > Hi, > > I looked into this as well this evening and didn't really understand what > they are > doing.
