VS16 libiconv_a.lib P1 P2 mismatch with php8

[fuyutsuki]

@cmb69 I tried the v142 14.20~14.28 build tools referring to #9, but all of them output the same error below.

libiconv_a.lib(iconv1.obj) : MSIL .netmodule または /GL を伴ってコンパイルされたモジュールが見つかりました。/LTCG を使用して再開始してください。リンカーのパフォーマンスを向上させるためには、コマンドラインに /LTCG を追加してください。

Stop.

It seems you are building with unsuitable dependencies. For the v142 build toolset, you need the vs16 dependencies from https://windows.php.net/downloads/php-sdk/deps/vs16/

[fuyutsuki]

Yes, I installing dependencies for vs16 using phpsdk_deps -u -t vs16 -b master -a x64 -f.

I rebuilt libiconv and sqlite3 using VS2019(14.28), but I get the following error.

$ nmake

Are you doing PGO builds?

[fuyutsuki]

No, according to the logs, PGO seems to be disabled.

Type 'nmake' to build PHP

[cmb69]

Okay. But I still don't understand why you get

fatal error C1900: 'P1' Version '20200803' と 'P2' Version '20190715' が一致しません。

link.exe is usually not picky regarding old libs (unless PGO instrumentation is requested). Or did you attempt that with an older VS version (i.e. < 14.28)?

Did you fully clean the build (nmake clean). Maybe there is an issue with the non-bundled extension? Did you try building without those first?

Yes, I was trying to build 14.20~14.28, it might have been 14.25.28610 at this time.
Now I using 14.28.

I did a nmake clean and rebuilt, but the result was the same.
By excluding the problematic --with-iconv and its dependency --with-libxml from configure, the build was successful, but jit cannot be used because of its dependency on iconv.

[cmb69]

Ah, yes, building with the latest libiconv and 14.27 may indeed not work. I'm facing the opposite issue: I often need to rebuilt libiconv (and a few others dependencies) to satify link.exe regarding PGO instrumentation after updating VS. However, building with the latest libiconv should work with 14.28 (at least VS 16.8.1 or later).

If you don't want to update to the latest VS, or it still doesn't work, download https://windows.php.net/downloads/php-sdk/deps/archives/vs16/x64/libiconv-1.16-2-vs16-x64.zip and unzip it to the dependencies folder (it has been build with 14.24).

I tried to build the latest version of libiconv v1.16-3 in 14.27 with php-sdk_deps, but I got the same error.

Also tried to build using the v1.16-2 that you provided in 14.24, but I got the same error with fatal error C1900.

The issue was that I was building with VisualStudio 2019 14.28, but the arch was built with win32.
I'm sorry for my mistake.
