Can you try if --with-upx-pack fixes the issue? I'm not sure this flag is really compatible with building a static library.

Thanks for the reminder, but the flag --with-upx-pack does not affect the result.

That's weird. FrankenPHP is using the embed SAPI and doesn't have this issue.
Would you be able to provide us a minimal reproducer?

[KingBes]

I added the whole thing to the zip package. embed-package

@KingBes I tested and it's working, but indeed there are some bugs need to be fixed.

I'm using FrankenPHP's default extension combination to build embed SAPI, and changed buildroot/bin/php-config file, set prefix="" to prefix="/path/to/buildroot". My working command:

# spc build command
bin/spc build apcu,bcmath,bz2,calendar,ctype,curl,dba,dom,exif,fileinfo,filter,ftp,gd,gmp,gettext,iconv,igbinary,imagick,intl,ldap,mbregex,mbstring,mysqli,mysqlnd,opcache,openssl,parallel,pcntl,pdo,pdo_mysql,pdo_pgsql,pdo_sqlite,pgsql,phar,posix,protobuf,readline,redis,session,shmop,simplexml,soap,sockets,sodium,sqlite3,ssh2,sysvmsg,sysvsem,sysvshm,tidy,tokenizer,xlswriter,xml,xmlreader,xmlwriter,zip,zlib,yaml,zstd --build-cli --build-micro --debug --enable-zts --build-embed

# edit php-config file using sed or vim or something.....

# compile, use musl-gcc (glibc gcc cannot be compiled statically)
/usr/local/musl/bin/x86_64-linux-musl-cc $(buildroot/bin/php-config --includes) -L$(pwd)/buildroot/lib a.c -lphp $(buildroot/bin/php-config --libs) -lm -lresolv -ldl -lpthread -lc -Wl,-rpath=$(pwd)/buildroot/lib -lpq -lpgport -lpgcommon -lgomp -lstdc++ -static

I found some bugs:

• Linking issue with PHP 8.4 and libpq #560 (strange bug but I do use the same way to make it work: Passing -lpq -lpgcommon -lpgport)
• php-config --version returns an empty string #563
• Missing prefix (may be defined in ./configure argument or inserting a patch function in php-config?)
• Missing build flags in php-config (Maybe adding -lresolv -lstdc++ these flags to php-config would be better?)
• Missing compiler guide (Most developers are using glibc-gcc incorrectly?)

I'm not sure about the habits of most developers who use embed, so it would be great if you or someone could provide some suggestions.
