Question

我正在创作的项目中运行make distcheck时遇到名义链接错误：

正如您所看到的，它正在使用g ++ 4.6和libtool 2.4.2在Ubuntu 12.04上出现。在使用g ++ 4.2.1和libtool 2.4.2（均通过自制软件安装）的OS X 10.7.4上，不会出现错误。它也没有出现在make check。

中

以下是Makefile.am的相关摘要：

# -- myprog --
#

lib_LTLIBRARIES += myproj/myprog/libmyprog.la
myproj_myprog_libmyprog_la_SOURCES = # ...
myproj_myprog_libmyprog_la_LIBADD = myproj/mylib/libmylib.la

sbin_PROGRAMS += myproj/myprog/myprog
myproj_myprog_myprog_SOURCES = myproj/myprog/main.cc
myproj_myprog_myprog_LDADD = myproj/myprog/libmyprog.la

# -- mylib --
#

lib_LTLIBRARIES += myprog/mylib/libmylib.la
myproj_mylib_libmylib_la_SOURCES = # ...

错误本身：

/usr/bin/ld: cannot find -lmylib
collect2: ld returned 1 exit status
libtool: install: error: relink `myproj/myprog/libmyprog.la' with the above command before installing it

我该如何解决这个问题？

Answer 1

简而言之，订单（显然）很重要：

# -- mylib --
#

lib_LTLIBRARIES += myprog/mylib/libmylib.la
myproj_mylib_libmylib_la_SOURCES = # ...

# -- myprog --
#

lib_LTLIBRARIES += myproj/myprog/libmyprog.la
myproj_myprog_libmyprog_la_SOURCES = # ...
myproj_myprog_libmyprog_la_LIBADD = myproj/mylib/libmylib.la

sbin_PROGRAMS += myproj/myprog/myprog
myproj_myprog_myprog_SOURCES = myproj/myprog/main.cc
myproj_myprog_myprog_LDADD = myproj/myprog/libmyprog.la

现在我的项目在所有提到的平台上构建（check和distcheck）。

libtool：install：error：在安装之前使用上面的命令重新链接`libmyprog.la'
