wrong target in MSYS2 toolchain

[dawn]

I'm trying the clangd language server and I'm experiencing the same issue as described in #2499.
I checked the compile_commands.json and compile_flags.txt files and I noticed that the target is i686-pc-windows-gnu instead of x86_64-pc-windows-gnu. My toolchain is the last MINGW-64 bit with gcc 10.1.0 obtained from MSYS2 with pacman (only 64 bit ).
Is there a place in settings where to change the target?
Thanks.

OS: Windows 10
CodeLite: 14.0.1

The target is auto detect by CodeLite.
You need to make sure that the compiler you selected for the project is indeed 64 bit.
Project settings -> General page -> Compiler.

CodeLite does the following to determine if your compiler is 64 bit or not:

1. Get list of built-in macros from the compiler (instead of 'gcc' it will use the full path for your compiler):

Code: Select all

echo | gcc -dM -E - > /tmp/file

2. Open /tmp/file and check for this line:

Code: Select all

#define _WIN64 1

If it is defined, then the selected compiler is indeed 64 bit, else, 32

I installed GCC 9.1 on my MSYS2 terminal, and indeed the logic to detect whether if the compiler is 64 bit is not working for this compiler

Code: Select all

pacman -S gcc
...
$ gcc --version
gcc (GCC) 9.1.0

Then I ran the command to list the built-in macros defined by this compiler, and indeed _WIN64 is not there
I could see however, that

Code: Select all

#define __x86_64__ 1
#define __amd64 1
#define __amd64__ 1

I changed the code to tests for this macros as well

Ok these are the settings in a small project that compiles correctly:
https://ibb.co/Fb74GPN
these are the build settings:
https://ibb.co/yqLCqxC
this is the echo command output:
https://ibb.co/cLXN8tX

This is the content of compile_flags.txt:
-IE:\cstack\libs\math\cglm\include
-IE:\cstack\libs\img\stb
-IE:\cstack\wks\mylib\lea_gui\include
-DUNICODE
-D__USE_MINGW_ANSI_STDIO
-DGLEW_STATIC
-target
i686-pc-windows-gnu

Creating a new test project with the last TDM toolchain (9.2.0) compile_flags.txt has the compiler includes too:
-IE:\cstack\compilers\TDM-GCC-920-64\lib\gcc\x86_64-w64-mingw32\9.2.0\include\c++
-IE:\cstack\compilers\TDM-GCC-920-64\lib\gcc\x86_64-w64-mingw32\9.2.0\include\c++\x86_64-w64-mingw32
-IE:\cstack\compilers\TDM-GCC-920-64\lib\gcc\x86_64-w64-mingw32\9.2.0\include\c++\backward
-IE:\cstack\compilers\TDM-GCC-920-64\lib\gcc\x86_64-w64-mingw32\9.2.0\include
-IE:\cstack\compilers\TDM-GCC-920-64\include
-IE:\cstack\compilers\TDM-GCC-920-64\lib\gcc\x86_64-w64-mingw32\9.2.0\include-fixed
-IE:\cstack\compilers\TDM-GCC-920-64\x86_64-w64-mingw32\include
-IE:\cstack\wks\mylib\lea_gui\include
-DUNICODE
-D__USE_MINGW_ANSI_STDIO
-target
x86_64-pc-windows-gnu

I hope that these info can be useful.

Updated: I've read now your answer

[eranif]

The problem is that TDM compiler *does* define the _WIN64, while the one that I have installed with pacman, does not.
This is already fixed in git master.

Sorry for the long wait, I tried again but the issue seems not to be fixed.

OS: Windows 10
CodeLite: 14.0.4

compile_command.json of a simple test:
[{
"file": "E:\\cstack\\wks\\mylib\\test\\main.c",
"directory": "E:\\cstack\\wks\\mylib\\test",
"command": "clang -c E:\\cstack\\wks\\mylib\\test\\main.c -o E:\\cstack\\wks\\mylib\\test\\main.c.o -target i686-pc-windows-gnu -I. -I. -g -O0 -Wall"
}]

gcc --version

#define _WIN64 1

The Msys2 compiler is correctly configured and projects build successfully.

does anyone else experience the problem described in the previous post?
