好吧，我在建立蘋果新OS X Yosemite上的gcc-4.9.2時遇到了麻煩。我不確定是否需要在OS X上構建gnu-gcc編譯器，因爲除了tesseract-3.0.1和我自己的一些wxWidgets應用程序之外，大多數其他軟件都編譯得很好。是否有鏗鏘聲無法編譯的某些程序/代碼功能？在OS X優勝美地上建造GCC-4.9.2
我的構建步驟如下：
cd build-gcc
../gcc-4.9.1/configure --program-prefix="gnu-" --prefix="/usr/local/gcc-4.9.1" --with-gmp="/usr/local" --with-mpfr="/usr/local" --with-mpc="/usr/local" CC=clang CXX=clang++
make
我的構建路徑和gcc源路徑不包含任何空白，我已經在/usr/local安裝GMP，MPFR和MPC。
我的生成輸出是：
clang++ -g -DIN_GCC -fno-exceptions -fno-rtti -fasynchronous-unwind-tables -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wno-format -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -fno-common -DHAVE_CONFIG_H -Wl,-no_pie -o cc1 c/c-lang.o c-family/stub-objc.o attribs.o c/c-errors.o c/c-decl.o c/c-typeck.o c/c-convert.o c/c-aux-info.o c/c-objc-common.o c/c-parser.o c/c-array-notation.o c-family/c-common.o c-family/c-cppbuiltin.o c-family/c-dump.o c-family/c-format.o c-family/c-gimplify.o c-family/c-lex.o c-family/c-omp.o c-family/c-opts.o c-family/c-pch.o c-family/c-ppoutput.o c-family/c-pragma.o c-family/c-pretty-print.o c-family/c-semantics.o c-family/c-ada-spec.o c-family/c-cilkplus.o c-family/array-notation-common.o c-family/cilk.o c-family/c-ubsan.o i386-c.o darwin-c.o \

配置輸出生成類型爲：x86_64-apple-darwin14.0.0，所以我不明白爲什麼會這樣。
非常感謝您的幫助。
GCC 4.9.2剛剛發佈。你可以嘗試一下;但是當然你需要所有必需的依賴關係。 – 2014-11-01 13:04:04
完全相同的錯誤，使用相同的庫，使用GCC 4.9.2 – 2014-11-01 13:42:17
也許你需要一些'--with-zlib'在'configure'時間... – 2014-11-01 13:43:49
