我正在尝试在我的笔记本电脑上安装 pygrib，以便我可以访问 GRIB 文件。由于我有一台 Windows 计算机，我必须使用 CYGWIN 环境来构建 Jasper、GRIB、OpenJPEG、PNG 和 pygrib 的库。我运行以下命令来获取我的系统构建类型：
$ gcc -dumpmachine
x86_64-pc-cygwin
然后我在 cywgin 中运行 ./configure 命令来编译 Jasper 库并得到以下输出：
$ ./configure --build='x86_64-pc-cygwin'
checking build system type... x86_64-pc-cygwin
checking host system type... x86_64-pc-cygwin
checking target system type... x86_64-pc-cygwin
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking for gcc... gcc
checking for C compiler default output file name... configure: error: C compiler cannot create executables
See `config.log' for more details.
我有一台 64 位机器，我很确定一切都为 cygwin 正确安装。如果 C 编译器无法创建可执行文件，任何有关如何解决此问题的帮助将不胜感激。这是“config.log”输出：
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.
It was created by jasper configure 1.900.1,
which was
generated by GNU Autoconf 2.59.
Invocation command line was
$ ./configure
