我有一个数学库(ADOL-C),需要链接到其他库(ColPack)以执行某些可选任务。
我可以在Linux中编译它们,在Windows中单独使用ADOl-C或ColPack,但是当我尝试在Windows中使用ColPack编译ADOL-C时(MinGW 32,ld 2.22)我有以下问题:
$ make
Making all in ADOL-C
make[1]: Entering directory `/c/tests/ADOL-C-2.3.0/ADOL-C'
[...]
CC int_reverse_s.lo
CC int_reverse_t.lo
CXXLD libadolc.la
*** Warning: This system can not link to static lib archive /usr/lib/libColPack.
la.
*** I have the capability to make that library automatically link in when
*** you link to this library. But I can only do this if you have a
*** shared version of the library, which you do not appear to have.

make[5]: *** [libadolc.la] Error 1
make[5]: Leaving directory `/c/tests/ADOL-C-2.3.0/ADOL-C/src'

我不能像在MinGW中那样提供动态库,即使我使用--enable-shared配置ColPack,我从来没有从其编译中获得任何共享库,只有libColPack。[a | la | lai]和ColPack.exe。
任何提示?
答案 0 :(得分:1)
花了一点时间,直到我解决了问题。
下载Colpack-1.0.8.tar.gz并使用以下环境对其进行测试
Msys / mingw 4.7.0。
正如您所说,您无法使用它来创建共享库。 过了一段时间,我发现了一个更复杂的解决方案。从这个基础上我发现了一个更短的方式。
简短解决方案:
打开配置
第#行 _ __ _ __ _ __ _ 更改 _ __ _ __ _ __ _ __ _ __ _ 到__
7660 enable_dlopen=no set it to yes
7663 enable_win32_dll=no set it to yes
7673 enable_shared=no set it to yes
7710 enable_static=yes set it to no
7717 enable_static=yes set it to no
8721 enable_shared_with_static_runtimes=no set it to yes
11797 enable_shared_with_static_runtimes_CXX=no set it to yes
保存并运行
./configure --disable-static --enable-shared
打开 libtool
第#行 _ __ _ __ _ __ _ 更改 _ __ _ __ _ __ _ __ _ __ _ 到__
5547 allow_undefined=yes set it to no
5550 allow_undefined=yes set it to no
保存并运行
make clean
make
.lib 目录中的现在应该是关注文件。

希望有所帮助!
注意:强>
没有测试过“make install”!
兼具静态和动态:
将libColPack.la,libColPack.lai和libColPack.dll.a移动到另一个文件夹。我们需要他们,他们将被覆盖。删除文件libColPack.la,目录级别更高。
将libtool文件更改回原始状态(2行)。
运行“make”
你将有一个新的libColPack.a
将libColPack.dll.a移回.libs
将两个先前移动的文件的内容与新的libColPack.la(.lai)合并。
将更新后的libColPack.la复制到目录级别更高的位置。
新的混音文件:libColPack.la
# libColPack.la - a libtool library file
# Generated by libtool (GNU libtool) 2.4
#
# Please DO NOT delete this file!
# It is necessary for linking the library.
# The name that we can dlopen(3).
dlname='libColPack-0.dll'
# Names of this library.
library_names='libColPack.dll.a'
....
# The name of the static archive.
old_library='libColPack.a'
....
通过这个技巧,您可以同时拥有静态和动态库。
