使用MinGW增强构建时出错

Question

I tried to build boost library using the MinGW's GCC version that comes with CodeBLocks (gccc v5.1) and i have the bin folder in the PATH. When i run

boostrap.bat mingw

or

boostrap.bat gcc

i get

execnt.c: In function 'try_wait_callback':
execnt.c:833:5: warning: implicit declaration of function 'UnregisterWait' [-Wimplicit-function-declaration]
 UnregisterWait( slot->wait_handle );

Reading a litte someone told me that my gcc version doesn't work to build boost so then i downloaded the last MinGW-w64 and copy its bin folder content into the MinGW's bin folder trying to "cheat"

if i do gcc -v

i can see i have the version 7.3

Now it throws me this error:

gcc: error: CreateProcess: No such file or directory

Answer 1

You should use MinGW-w64, without the step "copy its bin folder content into the MinGW" !

You want to avoid using the pre-fork MinGW entirely. Download and install MinGW-w64 again and , if you want, add it to Code::Blocks .

Note that there are some sites providing MinGW-w64 and Boost bundles.

Answer 2

I had the same problem with MinGW provided with Code::Block. So I have to add to recomendations important details. To build Boost.build tool:

1. After installation of minGW-w64 in NEW directory you need to delete entry of old MinGW\\bin directory from PATH environment variable and add new entry with something like "C:\\MinGW-w64\\bin" entry.
2. By some reason starting commands in command line under user or administrator didn't work as supposed in Boost documentation, but if start terminal from shortcut provided by MinGW-w64 - commands of Boost can finish building. (Command "bootstrap.bat gcc")
3. Then Boost documentation recomends "b2 install --prefix=PREFIX" but I had to add parameter like "b2 install --prefix=PREFIX toolset=gcc" also in terminal started from MinGW-w64 shortcut.
4. Since I wanted to use MinGW32 of Code::Blocks in my projects (for other compatibility reasons), again I had to skip MinGW-w64 from availability (I had just renamed dir of MinGW-w64, you can delete entry from PATH) and to restore MinGW32 entry in PATH variable. Also I added Boost build tool "bin" dir into PATH. So I had got Boost.Build tool ready to use (builded by MinGW-w64 compiler)

To build Boost libraries' binaries:

5. Then I started terminal under administrator, changed dir to boost root directory and then use the last command like "b2 --build-dir=build-directory toolset=gcc --build-type=complete stage" (where build-directory is of your choice)

And at last I'd got the result:

...failed updating 1334 targets...

...skipped 732 targets...

...updated 2873 targets...

Where I could find necessary for me files of Boost filesystem like

libboost_filesystem-mgw51-mt-x32-1_67.dll

libboost_filesystem-mgw51-mt-s-x32-1_67.a

libboost_filesystem-mgw51-mt-x32-1_67.a

etc.

I didn't test them yet, but this can help to others to build Boost.
