Description (last modified by ryandesign (Ryan Carsten Schmidt))

harfbuzz-icu build fails with this error:

libtool: compile:  /usr/bin/llvm-g++-4.2 -DHAVE_CONFIG_H -I. -I.. -D_THREAD_SAFE -pthread -I./hb-ucdn -I/opt/local/include -pipe -Os -arch x86_64 -fno-rtti -fno-exceptions -Wcast-align -fvisibility-inlines-hidden --std=c++0x -MT libharfbuzz_la-hb-blob.lo -MD -MP -MF .deps/libharfbuzz_la-hb-blob.Tpo -c hb-blob.cc  -fno-common -DPIC -o .libs/libharfbuzz_la-hb-blob.o
cc1plus: error: unrecognized command line option "-std=c++0x"

I am not sure if complier complains about extra "-" in --std=c++0x.

What version of Xcode are you using? Most (all?) versions of Xcode on Lion should be using clang, not llvm-gcc-4.2.

Port: icu added

--std=c++0x does not appear in the harfbuzz source code, but does appear in the pkg-config files installed by the icu port. You're right, that extra leading hyphen does look suspicious.

comment:6 Changed 10 years ago by ryandesign (Ryan Carsten Schmidt)

But llvm-g++-4.2 probably just doesn't support the C++11 standard that -std=c++0x calls for.

It seems wrong that icu is putting that flag in its pkg-config files. icu cannot know whether the compiler used to compile something using those pkg-config files supports C++11 or not.

The typo in the argument (--std should be -std) is already reported upstream: http://bugs.icu-project.org/trac/ticket/11413

I have reported this problem upstream: http://bugs.icu-project.org/trac/ticket/11455

You should update to Xcode 4.6.3.

I had forgotten that Xcode 4.1 was the first version for Lion, which did not include clang, so it defaulted to llvm-gcc-4.2. In addition, in r118085 we changed the default compiler in MacPorts for Xcode 4.2.x from clang to llvm-gcc-4.2. This was meant to help Snow Leopard, where Xcode 4.2 is an unusual configuration, not well tested, and the only one that was defaulting to clang, and a very old version of clang at that.

Well, that's wrong: clang existed in Xcode 4.1, we just weren't defaulting to it because it was still early in clang's development and at that time llvm-gcc-4.2 still worked better.

Summary: harfbuzz-icu 0.9.37_0 build fails on 10.7.5harfbuzz-icu @0.9.37_0: cc1plus: error: unrecognized command line option "-std=c++0x"

Has duplicates #48719, #50254, #50695. As mentioned above, this is an icu bug. The upstream bug report has not yet been closed, so updating icu to 56.1 probably won't help. I can try to patch icu to fix this.

This problem should only affect users of Xcode versions 4.0 through 4.2 inclusive, which are the only ones where MacPorts defaults to using llvm-g++-4.2. On Snow Leopard, it is recommended to use Xcode 3.2.6, and on Lion it is recommended to use Xcode 4.6.3; neither of those should experience this problem.

Given that harfbuzz and harfbuzz-icu build without issue on 10.7.5 now, it would seem this ticket could be closed:

Replying to kencu:

Given that harfbuzz and harfbuzz-icu build without issue on 10.7.5 now, it would seem this ticket could be closed:

No. The bug is that icu puts -std=... flags in its .pc files and -config script. icu @58.2 still does that. We have not updated to newer versions of icu because they require C++11. Now that we have the cxx11 1.1 portgroup, maybe it would be ok to update icu to a newer version, but I don't know if that would fix this bug; the upstream ticket is still open.

The originally reported build failure of harfbuzz-icu with llvm-gcc-4.2 won't happen anymore because the harfbuzz port now blacklists llvm-gcc-4.2.

Resolution: wontfix
Status: assignedclosed

In the mean time, we have updated to icu 65 which requires C++11. As such, it is understandable that -std=c++11 appears in its pkg-config files and the icu-config script.
