This reinstates and adjusts commit e3d0fcbf7e55e8cbe8d0a1c5a24d73f341d7243b. * gnu/packages/patches/gcc-libiberty-printf-decl.patch: New file. * gnu/packages/gcc.scm (gcc-5)[source]: Use it. [patches]: Add "gcc-arm-bug-71399.patch". (gcc): Switch to GCC-5. * gnu/packages/commencement.scm (libstdc++-boot0): New variable. (gcc-boot0)[inputs]: Add it. (gcc-toolchain-4.9): Switch to GCC-4.9. (gcc-toolchain-5): Switch to GCC-FINAL. * gnu/local.mk (dist_patch_DATA): Add 'gcc-libiberty-printf-decl.patch'. --- gnu/local.mk | 1 + gnu/packages/commencement.scm | 27 +++++++++++++++++++-- gnu/packages/gcc.scm | 5 ++-- .../patches/gcc-libiberty-printf-decl.patch | 28 ++++++++++++++++++++++ 4 files changed, 57 insertions(+), 4 deletions(-) create mode 100644 gnu/packages/patches/gcc-libiberty-printf-decl.patch (limited to 'gnu') diff --git a/gnu/local.mk b/gnu/local.mk index fdd5e3c81e..79d6b14a2b 100644 --- a/gnu/local.mk +++ b/gnu/local.mk @@ -546,6 +546,7 @@ dist_patch_DATA = \ %D%/packages/patches/gcc-arm-bug-71399.patch \ %D%/packages/patches/gcc-arm-link-spec-fix.patch \ %D%/packages/patches/gcc-cross-environment-variables.patch \ + %D%/packages/patches/gcc-libiberty-printf-decl.patch \ %D%/packages/patches/gcc-libvtv-runpath.patch \ %D%/packages/patches/gcc-strmov-store-file-names.patch \ %D%/packages/patches/gcc-5.0-libvtv-runpath.patch \ diff --git a/gnu/packages/commencement.scm b/gnu/packages/commencement.scm index 2431babcad..1238f5cf5b 100644 --- a/gnu/packages/commencement.scm +++ b/gnu/packages/commencement.scm @@ -172,6 +172,26 @@ ,cf))))) (inputs %boot0-inputs)))) +(define libstdc++-boot0 + ;; GCC's libcc1 is always built as a shared library (the top-level + ;; 'Makefile.def' forcefully adds --enable-shared) and thus needs to refer + ;; to libstdc++.so.
