MinGW Building Gdal 2.1.2

Two days ago, someone asked me on the Oschian MinGW compile gdal some problems, and then I simply compiled once, recording the compilation process.
This article was written in May 2017, when there was a draft box, which was only seen today. It may not be available for the latest version now.

1. Preparation

1, install MinGW, I installed is the version of Mingw-w64 x86_64-7.1.0-win32-seh-rt_v5-rev0 .
2. Prepare a Unix-like simulation run environment. I use Git's msys directly here, you can also download Cygwin.
3, download and decompression gdal source code

Note:the installation path of the MinGW must have no spaces, and if so, the compiler will not be found after compilation (absolute paths must be specified, and the paths need to be enclosed in quotation marks). Gdal the source code decompression path also do not have spaces.

2. Generate makefile

In the Msys environment, enter the gdal-2.1.2 source directory, run the command to generate the Gnumakefile file

# 将mingw的路径导入环境变量PATHexport PATH=$PATH:/c/mingw-w64/x86_64-7.1.0-win32-seh-rt_v5-rev0/mingw64/bin# 生成Makefile文件./configure --prefix=/z/gdal_2.1.2_mingw64 --without-libtool## --prefix 指定安装路径## --without-libtool 不使用libtool（因为我当前环境没有）## 默认是静态库和动态库都生成，使用libtool可能只能生成静态库，因为它不知道在当前平台如何生成动态库。

Attention
The above procedure will generate and file normally without GNUMakefile errors GDALmake.opt .
Because we do mingw64 not have a path to identify /c/xxx such paths (this is the path under Msys), we need to modify the GDALmake.opt file to GDAL_ROOT Modify the value in C:\xxx this form.

3. Compiling

Run the following command to compile

mingw32-make

4, the compilation encountered errors and solutions

The following error occurred during compilation

1. When the static library is generated arPrompt argument list too long

This can be done by modifying the gdal_obj variable in the gnumakefile file by splitting the original gdal_obj into multiple, and then The action of the Gdal_slib target is modified to generate multiple static libraries and then synthesize one.
Because of this large amount of modification, I do not modify, directly outside the use of command generation LIBGDAL.A . My source directory here is z:/gdal-2.1.2 .

Note: the parameters used when generating four static libraries are sr , this means that one is generated ranlib (only packaging .o files, not processing. o symbol table). When generated later libgdal.a , parameters are used, which means that the r members of the static library are updated after packaging __.SYMDEF .

2. When the dynamic library is generated g++Prompt argument list too long

The error here is the same as the reason for generating a static library, and the solution is similar to the above.
You can see the action of the generated target GDAL_LIB , the variables used (dependent. O and. A) GDAL_SLIB are consistent with the build. Because we have already generated,,, and so on, basepart.a appspart.a so we ogrpart1.a ogrpart2.a can create the dynamic library directly (the suffix is changed to DLL).

g++ -shared basepart.a appspart.a ogrpart1.a ogrpart2.a -lodbc32 -lodbccp32 -lz -lpthread -lm  -lws2_32 -liconv -o Z:/gdal-2.1.2/libgdal.dll

Note: because of the previous creation of the basepart.a file, AR uses the parameters to be sr successful. If the parameter is used r , the following error is reported:

basepart.a: error adding symbols: Archive has no index; run ranlib to add one

Also note that the above link uses the -liconv parameter, if not in the generated makefile, the following error will be reported
