Did you run revdep-rebuild --library 'libstdc++.so.6' -- --exclude gcc ? I had the same issue and this solved it (as described in portage news and in https://wiki.gentoo.org/wiki/Upgrading_from_gcc-4.x_to_gcc-5.x#Critical_news ). However, now I am getting these errors x86_64-pc-linux-gnu-g++ -MMD -MF obj/third_party/zlib/zip/zip.o.d -DV8_DEPRECATION_WARNINGS -DUSE_UDEV -DUI_COMPOSITOR_IMAGE_TRANSPORT -DUSE_AURA=1 -DUSE_PANGO=1 -DUSE_CAIRO=1 -DUSE_GLIB=1 -DUSE_NSS_CERTS=1 -DUSE_X11=1 -DDISABLE_NACL -DFULL_SAFE_BROWSING -DSAFE_BROWSING_CSD -DSAFE_BROWSING_DB_LOCAL -DCHROMIUM_BUILD -DENABLE_MEDIA_ROUTER=1 -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -DNDEBUG -DNVALGRIND -DDYNAMIC_ANNOTATIONS_ENABLED=0 -DGLIB_VERSION_MAX_ALLOWED=GLIB_VERSION_2_32 -DGLIB_VERSION_MIN_REQUIRED=GLIB_VERSION_2_26 -I../.. -Igen -Igen/shim_headers/minizip_shim -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -fno-strict-aliasing --param=ssp-buffer-size=4 -fstack-protector -Wno-builtin-macro-redefined -D__DATE__= -D__TIME__= -D__TIMESTAMP__= -funwind-tables -fPIC -pipe -m64 -march=x86-64 -pthread -Wall -Wno-unused-local-typedefs -Wno-maybe-uninitialized -Wno-missing-field-initializers -Wno-unused-parameter -O2 -fno-ident -fdata-sections -ffunction-sections -g0 -fvisibility=hidden -fvisibility-inlines-hidden -std=gnu++11 -Wno-narrowing -fno-rtti -fno-exceptions -O2 -pipe -march=native -fno-delete-null-pointer-checks -c ../../third_party/zlib/google/zip.cc -o obj/third_party/zlib/zip/zip.o In file included from /usr/include/minizip/unzip.h:55:0, from gen/shim_headers/minizip_shim/third_party/zlib/contrib/minizip/unzip.h:5, from ../../third_party/zlib/google/zip_internal.h:20, from ../../third_party/zlib/google/zip.cc:17: /usr/include/minizip/ioapi.h:135:51: error: expected initializer before ‘_Z_OF’ typedef voidpf (ZCALLBACK *open_file_func) _Z_OF((voidpf opaque, const char* filename, int mode)); ^ /usr/include/minizip/ioapi.h:136:51: error: expected initializer before ‘_Z_OF’ typedef uLong (ZCALLBACK *read_file_func) _Z_OF((voidpf opaque, voidpf stream, void* buf, uLong size)); ^ /usr/include/minizip/ioapi.h:137:51: error: expected initializer before ‘_Z_OF’ typedef uLong (ZCALLBACK *write_file_func) _Z_OF((voidpf opaque, voidpf stream, const void* buf, uLong size)); ^ /usr/include/minizip/ioapi.h:138:51: error: expected initializer before ‘_Z_OF’ typedef int (ZCALLBACK *close_file_func) _Z_OF((voidpf opaque, voidpf stream));
Rebuilding dev-libs/re2 solved my problem. Thanks!
