issue building plugin #513

labba · 2020-06-30T15:38:33Z

now that i know how to compile the environment, i have added to the configuration "--enable-plugin" and recompiled it successfully.

to create plugin there is a need to compile it as follow:

first need to locate the plugin dir:

g++ -print-file-name=plugin
C:/msys64/home/gcc/mingw-gcc-8.3.0/x86_64-830-win32-sjlj-rt_v7/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.3.0/plugin

after locating the plugin dir, i have converted the "/" to "\" and compile a plugin example:
while set the plugin dir to the variable ${PLUGIN_DIR}

g++ -I${PLUGIN_DIR}/include -fPIC -shared -Wl,--export-all-symbols my_first_gcc_plugin.cc -o
 my_plugin.dll  ${PLUGIN_DIR}\cc1.exe.a

you can see the source code for the example here:
https://raw.githubusercontent.com/rofirrim/gcc-plugins/master/01_first/my_first_gcc_plugin.cc

the error i'm getting is:


In file included from C:/msys64/home/gcc/mingw-gcc-8.3.0/x86_64-830-win32-sjlj-rt_v7/mingw64/lib/gcc/x86_64-w64-mingw32/8.3.0/plugin

10: fatal error: gmp.h: No such file or directory
 #include <gmp.h>
          ^~~~~~~
compilation terminated.

i seen that when i use some other distribution that also have plugin enable it's working fine:
I used one of the already compiled version from: https://gcc-mcf.lhmouse.com/
i have used the mingw-w64-gcc-mcf_20200324_9.3.1_x86

i couldn't understand what is the main difference between those 2 builds that make success build only on lhmouse but fail on this compilation..

The text was updated successfully, but these errors were encountered:

niXman · 2020-07-01T07:48:23Z

I think there is some kind of patch that is not used here...
or diff binutils/gcc options used...

labba · 2020-07-01T07:55:40Z

this is the configuration of GCC i dont know how to get the configuration of binutils (if you will let me know i will post them as well):

Using built-in specs.

Thread model: mcf
gcc version 9.3.1 20200323 (GCC with MCF thread model, built by LH_Mouse.)

i don't believe that the thread model is the one that makes the difference ..

when searching for "gmp.h" in the LH Mouse project i do locate it here:
"mingw-w64-gcc-mcf_20200324_9.3.1_x86\mingw32\include\gmp.h"

but in your project when i search for the same file, i fail in locating it in the final package ..
also when i look on the overall files inside of the "mingw-gcc-8.3.0\x86_64-830-win32-sjlj-rt_v7\mingw64\include" its very slim and missing a lot of includes ...

why is that ?

niXman · 2020-07-01T08:50:00Z

when searching for "gmp.h" in the LH Mouse project i do locate it here:
"mingw-w64-gcc-mcf_20200324_9.3.1_x86\mingw32\include\gmp.h"

because he delivers these files in the final archive, but I do not. you are the first who need these files.

why is that ?

because you comparing the two diff folders: the first is the archive with the final build, but the second - is the temporary directory used during the build process.

labba · 2020-07-01T09:25:19Z

thanks!
apparently,it is mandatory when developing plugins ..

what do i need to change in order to do all the copying of all the includes from all the packages to the include folder?

this is the lhmouse folder content:

copying the needed include won't be enough .. even when i copy the required missing header it's still give me the same error that it's not found .. any idea why ?

niXman · 2020-07-02T09:25:43Z

I don’t remember what to copy and where, I need to figure it out myself, but I don’t have time now, sorry...

niXman · 2020-07-02T10:22:55Z

@labba can you provide me an archive of the build directory? I think it is $HOME/mingw-gcc-8.3.0

labba · 2020-07-03T06:34:56Z

thanks for the help!

i have uploaded it here: https://mega.nz/file/nkhkQAzB#ZLuspa19Qvqrx8nTriChm6Wm4nJtiW2SSUVEAo8h7fk

labba · 2020-07-10T12:05:41Z

hi,
any luck with what i have uploaded ?

niXman · 2020-07-10T13:16:45Z

sorry, was on vacation.

will check in the morning.

niXman · 2020-07-12T13:33:06Z

I think you need to copy the headers from /mingw-gcc-8.3.0/prerequisites/x86_64-w64-mingw32-static/include into target mingw64/x86_64-w64-mingw32/include and libs from /mingw-gcc-8.3.0/prerequisites/x86_64-w64-mingw32-static/lib into target mingw64/x86_64-w64-mingw32/lib

labba · 2020-07-13T05:59:22Z

i will give it a try and will update
Thanks!

usually in the other compilation environment i never get any warnings .

niXman · 2020-07-13T08:23:50Z

please provide me the source code of your plugin and command line you use for compiling it.

labba · 2020-07-13T13:21:34Z

i gave everything in the very first post of the question the source and the commands i have done.
re-posting it again:

to create plugin there is a need to compile it as follow:

first need to locate the plugin dir:

g++ -print-file-name=plugin
C:/msys64/home/gcc/mingw-gcc-8.3.0/x86_64-830-win32-sjlj-rt_v7/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.3.0/plugin

now that we have the plugin dir we can use it so i saved it to a var named: ${PLUGIN_DIR}
and now we can compile the plugin

you can see the source code for the example here:
https://raw.githubusercontent.com/rofirrim/gcc-plugins/master/01_first/my_first_gcc_plugin.cc

and this is the command we need to invoke:

g++ -I${PLUGIN_DIR}/include -fPIC -shared -Wl,--export-all-symbols my_first_gcc_plugin.cc -o
 my_plugin.dll  ${PLUGIN_DIR}/cc1.exe.a

the error i'm getting is:

any luck reproducing the issue ?

labba · 2020-09-01T18:08:01Z

sorry for bothering on this again , but it's been a while i i thought maybe it was forgotten ..

niXman · 2020-09-07T08:28:11Z

the easiest way is to set the compiler you built as the default compiler.
after that configure and build (configure ... && make && make install) the required libraries by specifying the required prefix.
for example: configure --prefix=/my_mingw_root/x86_64-w64-mingw32
