c++ - 编译gcc 5.4.0后要导出的头文件夹

Question

我已经编译了gcc 5.4.0（make，make install到非根文件夹），并将其导出到相同基本发行版的其他计算机上。但是，当我尝试在第二台计算机上编译hello world时，出现了stdio.h错误，并且级联到cstdio等。

对于gcc，我根据--help将configure --prefix=/home/mybin --bindir=/home/mybin/bin --libdir=/home/mybin/lib等用于所有可用文件夹。

在gcc编译机上，似乎源文件夹/home/tmp/gcc-5.4.0/libstdc++-v3/include已安装到带有所有子目录的--includedir=/home/mybin/include文件夹中。

在5.4.0编译器上搜索stdio.h，我得到几个包含stdio.h版本的文件夹。

/home/tmp/gcc-5.4.0/libstdc++-v3/include/tr1/stdio.h
/home/tmp/gcc-5.4.0/libstdc++-v3/include/c_compatibility/stdio.h
/home/tmp/gcc-5.4.0/fixincludes/tests/base/rtldef/stdio.h
/home/tmp/gcc-5.4.0/fixincludes/tests/base/stdio.h
/home/tmp/gcc-5.4.0/libssp/ssp/stdio.h
/home/tmp/gcc-5.4.0/gcc/testsuite/gcc.dg/cpp/usr/include/stdio.h

并且 --prefix=/home/mybin/的搜索返回

/home/mybin/lib/gcc/x86_64-unknown-linux-gnu/5.4.0/include/ssp/stdio.h
/home/mybin/include/c++/5.4.0/tr1/stdio.h
/home/mybin/include/c_compatibility/stdio.h

所以我将``--prefix = / home / mybin /`文件夹复制到新机器上并尝试使用

gcc -Wall -I/home/mybin/include/c_compatibility /home/myuser/test.c -o /home/myuser/hello

这给

In file included from /home/myuser/test.c:3:0:
/home/mybin/include/c_compatibility/stdio.h:29:18: fatal error: cstdio: No such file or directory

但是我有

/home/mybin/include/c++/5.4.0/tr1/cstdio
/home/mybin/include/c++/5.4.0/cstdio
/home/mybin/include/c_std/cstdio
/home/mybin/include/c/cstdio

如此更新为

gcc -Wall -I/home/mybin/include/c_compatibility -I/home/mybin/include/c_std  /home/myuser/test.c -o /home/myuser/hello
In file included from /home/mybin/include/bits/c++config.h:482:0,
                 from /home/mybin/include/c_std/cstdio:44,
                 from /home/mybin/include/c_compatibility/stdio.h:29,
                 from /home/myuser/test.c:3:
/home/mybin/include/bits/os_defines.h:39:22: fatal error: features.h: No such file or directory
compilation terminated.

但是我确实有 /home/mybin/include/c++/5.4.0/parallel/features.h

gcc -Wall -I/home/mybin/include/c_compatibility -I/home/mybin/include/c_std  /home/myuser/test.c -o /home/myuser/hello

我也尝试导出LD配置标志

我如何知道要导出的文件夹以及从同一基本映像制成的其他计算机，以便可以使用此版本进行编译。为什么找不到包含项或将其弄糊涂？

我正在使用centos7

不，如果您拥有安装目录，则不需要sudo。我们正在尝试确定您是否已完成安装步骤...。
