ruby.wasmのビルド中にruby/zlibのconfigureに失敗する

ビルド終盤の linking ruby のあとでエラーが起きています。

zlibがインストールされていない？

dpkg -l |grep zlibを実行すると

ledsun@MSI:~/ruby.wasm[1]►dpkg -l |grep zlib
ii  zlib1g:amd64                        1:1.2.11.dfsg-2ubuntu9.2                     amd64        compression library - runtime
ii  zlib1g-dev:amd64                    1:1.2.11.dfsg-2ubuntu9.2                     amd64        compression library - development

zlibはインストールされています。

sudo apt --reinstall install zlib1g zlib1g-devしてみます。変わりません。

エラーログファイルをみる

build/wasm32-unknown-wasi/head-wasm32-unknown-wasi-full-js-debug/ext/zlib/mkmf.logをみます。 build/wasm32-unknown-wasi/head-wasm32-unknown-wasi-full-js-debug/ext/zlib/mkmf.log · GitHub

15~16行目

conftest.c:3:10: fatal error: 'zlib.h' file not found
#include <zlib.h>

echo '#include <zlib.h>' | gcc -o a.out -E - は成功します。 zlib.hが見えなくなる条件があるようです。

ここにzlib.hがないのでしょうか？

locate zlib.hを実行すると

/usr/include/zlib.hがあります。コピーしたらいいのかな？

cp /usr/include/zlib.h /home/ledsun/ruby.wasm/build/wasm32-unknown-wasi/head-wasm32-unknown-wasi-full-js-debug/.ext/include/wasm32-wasi /.してみます。変わりません。

ファイルが見つかってないわけじゃないのかなあ？
