Issue #19331 has been updated by nobu (Nobuyoshi Nakada). Status changed from Open to Feedback I tried the exactly same commands on Ubuntu 22.04, but couldn't reproduce the result of `grep`. And the command to build windows_31j.so seems using the expected options. ``` gcc -shared -o .ext/x86_64-linux/enc/windows_31j.so enc/windows_31j.o -L. -L. -L. -fstack-protector-strong -rdynamic -Wl,-export-dynamic -Wl,--no-as-needed -Wl,--compress-debug-sections=zlib -Wl,-rpath,/usr/ruby/3.1/lib/amd64 -L/usr/ruby/3.1/lib/amd64 -lruby -lm ``` ---------------------------------------- Bug #19331: --enable-rpath results in incorrect RPATH in Ruby 3.1.3 https://bugs.ruby-lang.org/issues/19331#change-101207 * Author: Kulikjak (Jakub Kulik) * Status: Feedback * Priority: Normal * ruby -v: 3.1.3 * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- I just updated Ruby from 3.1.2 to 3.1.3 and found out that all .so libraries from the enc directory have wrong RPATH/RUNPATH (when building with `--enable-rpath`). I first hit this on Solaris, but my testing on Linux resulted in the same thing. It can be easily reproduced with the following: ``` wget http://cache.ruby-lang.org/pub/ruby/3.1/ruby-3.1.3.tar.gz tar xzf ruby-3.1.3.tar.gz cd ruby-3.1.3 ./configure --prefix=/usr/ruby/3.1 --mandir=/usr/ruby/3.1/share/man --bindir=/usr/ruby/3.1/bin --sbindir=/usr/ruby/3.1/sbin --libdir=/usr/ruby/3.1/lib/amd64 --with-rubylibprefix=/usr/ruby/3.1/lib/ruby --enable-shared --enable-rpath /usr/bin/make -j 16 -l 32 objdump -x ./.ext/x86_64-linux/enc/windows_31j.so | grep RPATH ``` While previously this resulted in the following output: `RPATH /usr/ruby/3.1/lib/amd64` in 3.1.3 it is wrongly set to the build directory: `RPATH /home/jkulik/rubytest/ruby-3.1.3` I tried looking for some obvious change but didn't find the core of this issue yet. All I found out is that generated `enc.mk` differs in `prefix` and `libdir` ``` -prefix = /usr/ruby/3.1 +prefix = /home/jkulik/rubytest/ruby-3.1.3 exec_prefix = $(prefix) -libdir = $(exec_prefix)/lib/amd64 +libdir = /home/jkulik/rubytest/ruby-3.1.3 ``` `rbconfig.rb` is similar in both versions, but when I print out `CONFIG` in `make_encmake.rb` right after `load File.expand_path("lib/mkmf.rb", dir)`, I can see the differences from above, so it's probably something in the `lib/mkmf.rb` file that changes that. I am seeing the same issue in the current latest ruby 3.1 branch cloned from github. -- https://bugs.ruby-lang.org/
