On my Raspberry PI computer I have compiled the tcc compiler from source (in /usr/local/src). When I link with a library in /usr/lib, tcc cannot find it so I need to add -L/usr/lib to the tcc command. How do I configure and make tcc to include /usr/lib in its library path?

pi@raspberrypi /usr/local/src/tcc-0.9.26 $ tcc -vv
tcc version 0.9.26 (ARM Hard Float Linux)
install: /usr/local/lib/tcc/
crt:
  /usr/lib/arm-linux-gnueabihf
libraries:
  /usr/lib/arm-linux-gnueabihf
  /lib/arm-linux-gnueabihf
  /usr/local/lib/arm-linux-gnueabihf
include:
  /usr/local/include
  /usr/local/include/arm-linux-gnueabihf
  /usr/include
  /usr/include/arm-linux-gnueabihf
  /usr/local/lib/tcc/include
elfinterp:
  /lib/ld-linux-armhf.so.3

这是编译 tcc 本身时的配置选项。如果要使用二进制 tcc 分发，则必须继续使用 -L 选项。

但是，自己编译 tcc 应该很容易。这些是粗略的步骤：

% git clone git://repo.or.cz/tinycc.git 
% cd tinycc 
% ./configure --libpaths=/usr/lib
% make

还有更多选择。看：

% ./configure --help
Usage: configure [options]
Options: [defaults in brackets after descriptions]

Standard options:
  --help                   print this message
  --prefix=PREFIX          install in PREFIX [/usr/local]
  --exec-prefix=EPREFIX    install architecture-dependent files in EPREFIX
                           [same as prefix]
  --bindir=DIR             user executables in DIR [EPREFIX/bin]
  --libdir=DIR             object code libraries in DIR [EPREFIX/lib]
  --tccdir=DIR             installation directory [EPREFIX/lib/tcc]
  --includedir=DIR         C header files in DIR [PREFIX/include]
  --sharedir=DIR           documentation root DIR [PREFIX/share]
  --docdir=DIR             documentation in DIR [SHAREDIR/doc/tcc]
  --mandir=DIR             man documentation in DIR [SHAREDIR/man]
  --infodir=DIR            info documentation in DIR [SHAREDIR/info]

Advanced options (experts only):
  --source-path=PATH       path of source code [/Users/miki/projects/tinycc-so]
  --cross-prefix=PREFIX    use PREFIX for compile tools []
  --sysroot=PREFIX         prepend PREFIX to library/include paths []
  --cc=CC                  use C compiler CC [gcc]
  --extra-cflags=          specify compiler flags [-Wall -g -O2]
  --extra-ldflags=         specify linker options []
  --strip-binaries         strip symbol tables from resulting binaries
  --disable-static         make libtcc.so instead of libtcc.a
  --disable-rpath          disable use of -rpath with the above
  --with-libgcc            use /lib/libgcc_s.so.1 instead of libtcc.a
  --enable-mingw32         build windows version on linux with mingw32
  --enable-cygwin          build windows version on windows with cygwin
  --enable-cross           build cross compilers
  --enable-assert          enable debug assertions
  --with-selinux           use mmap for exec mem [needs writable /tmp]
  --sysincludepaths=...    specify system include paths, colon separated
  --libpaths=...           specify system library paths, colon separated
  --crtprefix=...          specify locations of crt?.o, colon separated
  --elfinterp=...          specify elf interpreter

您可能还希望将 tcc 安装到配置的目录中。

% make install

事实证明，我们需要使用该libpaths选项并指定默认库目录（来自 的输出tcc -vv）。我们还可以添加标准目录/lib和/usr/local/lib：

# ./configure --libpaths=/usr/local/lib/arm-linux-gnueabihf:/lib/arm-linux-gnueabihf:/usr/lib/arm-linux-gnueabihf:/usr/local/lib:/lib:/usr/lib
