[英]Cygwin pkg-config/protobuf filepath issues
I'm trying to compile & install a C++ library using Cygwin. 我正在尝试使用Cygwin编译和安装C ++库。 I've properly installed the library's dependencies.
我已经正确安装了库的依赖项。 However, ./configure is throwing an error:
但是,。/ configure引发错误:
checking for protobuf... no configure: error: Package requirements (protobuf >= 3.3) were not met: 正在检查protobuf ...否配置:错误:不满足软件包要求(protobuf> = 3.3):
No package 'protobuf' found 找不到软件包“ protobuf”
Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. 如果您以非标准前缀安装软件,请考虑调整PKG_CONFIG_PATH环境变量。
I then checked config.log, and found a suggestion to point PKG_CONFIG_PATH
at the lib/pkgconfig
directory. 然后,我检查了config.log,并发现了将
PKG_CONFIG_PATH
指向lib/pkgconfig
目录的建议。 I promptly set PKG_CONFIG_PATH
to /usr/local/lib/pkgconfig
, the directory where protobuf.pc
is located on my system. 我立即将
PKG_CONFIG_PATH
设置为/usr/local/lib/pkgconfig
,即protobuf.pc
在系统上的目录。 The error persisted. 错误仍然存在。 Some checking of similar questions here showed that some people had to use the Windows filepath, so I switched
PKG_CONFIG_PATH
to c:\\\\cygwin64\\\\usr\\\\local\\\\lib\\\\pkgconfig
. 在这里对类似问题的一些检查表明,有些人必须使用Windows文件路径,因此我将
PKG_CONFIG_PATH
切换为c:\\\\cygwin64\\\\usr\\\\local\\\\lib\\\\pkgconfig
。 The error persisted. 错误仍然存在。 I even tried setting
PKG_CONFIG_PATH
to /cygdrive/c/cygwin64/usr/local/lib/pkgconfig
. 我什至尝试将
PKG_CONFIG_PATH
设置为/cygdrive/c/cygwin64/usr/local/lib/pkgconfig
。 Which didn't work. 哪个没有用。
What am I doing wrong here? 我在这里做错了什么?
(Since I can't comment yet, I guess I need to leave this as an answer?) (由于我无法发表评论,我想我需要将此作为答案吗?)
After installing the libprotobuf-devel package from the cygwin setup.exe, I could run pkg-config --list-all
and see protobuf
listed in the output. 从cygwin setup.exe安装libprotobuf-devel软件包后,我可以运行
pkg-config --list-all
并在输出中看到protobuf
。 Also, pkg-config --print-provides protobuf
returns protobuf = 3.3.1
. 同样,
pkg-config --print-provides protobuf
返回protobuf = 3.3.1
。 Are you getting the same output? 您得到相同的输出吗?
I would also look at the configure
script to see what it's trying to check. 我还将查看
configure
脚本,以查看其要检查的内容。 Opening up configure
and searching for protobuf
or checking for protobuf
should get you close to the actual check. 打开
configure
并搜索protobuf
或checking for protobuf
应该可以使您接近实际检查。 Maybe configure
is trying to do something weird. 也许
configure
正在尝试做一些奇怪的事情。
Lastly, at least on my cygwin install, I do not have a /usr/local/lib/pkgconfig
directory. 最后,至少在我的cygwin安装中,我没有
/usr/local/lib/pkgconfig
目录。 If you installed protobuf from source, maybe you could try the cygwin devel package (libprotobuf-devel) and see if that helps. 如果您从源代码安装了protobuf,也许您可以尝试使用cygwin devel软件包(libprotobuf-devel),看看是否有帮助。
