使用MXE交叉编译KDSoap

Question

在Ubuntu15.04上的MXE中交叉编译的qt5：

make qt5

然后克隆KDSoap存储库，并尝试交叉编译它：

cmake -DCMAKE_TOOLCHAIN_FILE=/data/hd1/repositories/mxe/usr/i686-w64-mingw32.static/share/cmake/mxe-conf.cmake /data/hd1/repositories/KDSoap

在make之后，还有链接器的问题

它们来自pcre、crypto、openssl、zlib和其他网站。

我尝试在CMakeFiles/kdsoap.dir/linklibs.rsp链接器命令中添加一个-lpcre。并手动重新运行链接(例如，在src/KDSoapClient中)：

/data/hd1/repositories/mxe/usr/bin/i686-w64-mingw32.static-g++   -O3 -DNDEBUG  -shared -o ../../bin/libkdsoap.dll -Wl,--out-implib,../../lib/libkdsoap.dll.a -Wl,--major-image-version,1,--minor-image-version,4 -Wl,--whole-archive CMakeFiles/kdsoap.dir/objects.a -Wl,--no-whole-archive @CMakeFiles/kdsoap.dir/linklibs.rsp

但是pcre-related链接错误并没有消失。

可以做些什么来进行更多的调查？或者有一个不同的过程来交叉编译基于Qt的代码？

Answer 1

只需尝试将-lpcre16添加到链接器命令。

Answer 2

这对我在CMakeLists.txt中很有效
