我有一个为 C++ OpenImageIO库 ( OpenImageiGO )提供绑定的 Go 库。我一直很高兴通过标准动态链接到 libOpenImageIO 来构建我的绑定，但现在我正在尝试静态链接。我遇到了一个问题，无论我尝试哪种标志组合，外部链接器都会失败并出现大量“未定义引用”错误。我似乎记得在过去看到过这个问题，说链接器看到符号的顺序存在问题。但我似乎无法再次找到此信息。
这是我最近构建尝试的一个简短示例，试图让它链接到 boost、OpenColorIO 和 OpenImageIO 的静态构建：
$ export CGO_CPPFLAGS="\
-I/path/to/boost/include \
-I/path/to/OpenColorIO/include \
-I/path/to/OpenImageIO/include"
$ export CGO_LDFLAGS="\
-L/path/to/boost/lib -lboost_thread_static -lboost_system_static \
-L/path/to/OpenColorIO/lib -lopencolorio \
-L/path/to/OpenImageIO/lib -lOpenImageIO"
$ go build -v -x --ldflags '-extldflags "-static"' github.com/justinfx/openimageigo
...
CGO_LDFLAGS="/path/to/boost/lib/libboost_system_static.a" "/path/to/boost/lib/libboost_thread_static.a" "/path/to/OpenColorIO/lib/libopencolorio.a" "/path/to/OpenImageIO/lib/libOpenImageIO.a" "-lstdc++" /vol/apps/go/1.3.0/pkg/tool/linux_amd64/cgo -objdir $WORK/github.com/justinfx/openimageigo/_obj/ -- -I/path/to/boost/include -I/path/to/OpenColorIO/include -I/path/to/OpenImageIO/include -I./cpp -I $WORK/github.com/justinfx/openimageigo/_obj/ -I/path/to/boost/include -I/path/to/OpenColorIO/include -I/path/to/OpenImageIO/include color.go imagebuf.go imagebufalgo.go imagecache.go imageinput.go imageoutput.go imagespec.go oiio.go roi.go

这里有一些精心挑选的错误，因为它是一个很长的输出：
/path/to/OpenImageIO/lib/libOpenImageIO.a(OpenImageIO_dist^src^libOpenImageIO^color_ocio.cpp.o): In function `ColorConfig':
/path/to/OpenImageIO/OpenImageIO_dist/src/libOpenImageIO/color_ocio.cpp:141: undefined reference to `OpenColorIO::v1::SetLoggingLevel(OpenColorIO::v1::LoggingLevel)'
...
/path/to/OpenImageIO/lib/libOpenImageIO.a(OpenImageIO_dist^src^libOpenImageIO^imagebufalgo_copy.cpp.o): In function `boost::shared_mutex::lock()':
/path/to/boost/include/boost/thread/pthread/shared_mutex.hpp:138: undefined reference to `boost::this_thread::disable_interruption::~disable_interruption()'
OpenImageIO 似乎无法找到 OpenColorIO 的参考资料。而且，OpenImageIO 似乎无法找到提升的参考。似乎链接过程中发生的事情的顺序并没有使 OpenColorIO 或增强符号对 OpenImageIO 可用，所以我得到了一堆符号错误。
我希望我正在做一些简单而愚蠢的事情，可以在我的构建过程中得到纠正。但是与外部库的 cgo 静态链接似乎比默认的动态链接方法更复杂。
更新#1
@james-henstridge 给出的答案是正确的，我几乎完全建成，除了最后一个打嗝。尽管我的顺序似乎正确，但我对yaml-cpp, required by 的引用却失败了。OpenColorIO
这是我最新的环境，在那里我完成了所有必须添加的显式静态库：
$ export CGO_CPPFLAGS="-I/usr/local/include -I/usr/include"
$ export CGO_LDFLAGS="\

更新#2
没关系更新＃1。它与问题特别相关，OpenColorIO而不是一般问题。
