I am trying to build NetCDF4 from source on MacOSX. When I run ./configure I get the error:
我正在尝试从MacOSX上的源代码构建NetCDF4。当我运行。/configure我得到错误:
checking for library containing H5Fflush... no
configure: error: Can't find or link to the hdf5 library. Use --disable-netcdf-4, or see config.log for errors.
I installed hdf5 before, and set the environment variables as:
我之前安装了hdf5，并设置环境变量为:
LDFLAGS=-L/opt/local/lib
CPPFLAGS=-I/opt/local/include
In /opt/local/lib I have these files:
在/opt/local/lib中我有这些文件:
libhdf5.8.dylib
libhdf5.a
libhdf5.dylib
libhdf5.settings
libhdf5_cpp.8.dylib
libhdf5_cpp.a
libhdf5_cpp.dylib
libhdf5_hl.8.dylib
libhdf5_hl.a
libhdf5_hl.dylib
libhdf5_hl_cpp.8.dylib
libhdf5_hl_cpp.a
libhdf5_hl_cpp.dylib
And in /opt/local/include I have:
在/opt/local/包括:
hdf5.h hdf5_hl.h
Why doesn't the configure script find the hdf5 library? I am happy to provide more information if needed!
为什么配置脚本没有找到hdf5库?如果需要，我很乐意提供更多的信息!
EDIT: My ultimate goal is to install netcdf4 for use as a Fortran module. I have tried installing everything through MacPorts, and it seemed to work, but when I tried to use it, the compiler told me that there was no netcdf.mod file, and sure enough there wasn't one to be found anywhere. It turns out that just typing:
编辑:我的最终目标是安装netcdf4作为Fortran模块。我尝试过在MacPorts中安装所有的东西，它看起来很有用，但是当我尝试使用它时，编译器告诉我没有netcdf。mod文件，当然，在任何地方都找不到。结果是:
sudo port install netcdf-fortran
only installs the library files, but doesn't create a .mod file, which I guess is needed. So I found out that other people had the same problem, and the advice given was to install it with gcc44, which did create a .mod file, but then my compiler told me that the .mod file was built with a different version of gfortran and it couldn't be used, so that's why I am trying to build it from scratch, but if someone has a faster option, I would be more than happy to try it!
只安装库文件，但不创建.mod文件，我想这是需要的。所以我发现其他人有同样的问题,给出的建议是与gcc44安装它,并创建一个mod文件名,然后我的编译器告诉我,不同版本的mod文件名建于gfortran无法使用,这就是为什么我想从头开始构建它,但如果有人更快的选择,我将乐意试试!

Ok, I finally figured it out. I reinstalled netcdf-fortran with macports, then the .mod file suddenly appeared, I then had the problem, however, that when running gfortran, it would tell me that netcdf.mod was compiled with a different version of fortran than the one I am using. (Macports uses 4.8), so got gcc48 from macports and am using gfortran-mp-4.8 to compile now and it works.
好吧，我终于明白了。我用macports重新安装了netcdf-fortran，然后这个.mod文件突然出现了，然后我遇到了问题，当运行gfortran时，它会告诉我netcdf。mod是用不同版本的fortran编译的，而不是我使用的版本。(Macports使用的是4.8)，因此从Macports获得gcc48，现在正在使用gfortran-mp-4.8进行编译，它可以工作。
Still don't know how to build all these things from scratch, but it works now at least!!!
仍然不知道如何从头开始构建所有这些东西，但是至少现在是有效的!!!

Typically, I see this when there is a downstream dependency that cannot be fulfilled. The test program created by configure is finding libhdf5, but compilation is still failing because it cannot find something like libz or libszip, depending on how your libhdf5 was compiled.
通常情况下，当存在无法实现的下游依赖时，我就会看到这种情况。通过configure创建的测试程序是找到libhdf5，但是编译仍然失败，因为它不能找到libzor或libszip之类的东西，这取决于您的libhdf5是如何编译的。
If you check your config.log file and look for the error, it will probably tell you something along the lines of 'unresolved symbol'. This will give a clue as to which library is missing. If it is linking against the statically-built libhdf5, you may need to add the appropriate library usingLDFLAGS.
如果你检查你的配置。日志文件并查找错误，它可能会告诉您一些“未解决的符号”。这将提供一个线索，关于哪个库丢失。如果它链接到静态构建的libhdf5，您可能需要添加适当的库usingLDFLAGS。
If you post the relevant portion of your config.log file, we may be able to help sort out what exactly is going wrong.
如果您发布了配置的相关部分。日志文件，我们也许能够帮助找出到底出了什么问题。
