Using gcc-9.3.0, mysql++-8.0.23 fails to compile with several ".../mysql/sql/item.cc:1742:10: error: 'm_sp' was not declared in this scope." Reproducible: Always Steps to Reproduce: 1. emerge =dev-db/mysql++-8.0.23 2. 3. Actual Results: Compile failure as stated. Expected Results: Successful emerge. This seems similar to https://bugs.mysql.com/bug.php?id=102654 "Debug mode causes mysql to fail with error: ‘m_sp’ was not declared." That one was closed as not a but, but a configuration issue with comment "Indeed. DBUG_OFF and NDEBUG must be in sync." I get the same failure with debug USE flag set or not, but I'm wondering if one of those two configure settings might actually need adjusting in the ebuild.
Created attachment 690594 [details] build.log (gzipped because of size) build.log with debug USE flag set. Let me know if you want build.log without debug, or other info.
Arghhh - this is mysql, not mysql++. I have no idea how my brain went out to lunch on that one.
More my bad. It compiles OK with -debug, so I suppose that makes it less critical, and does support the idea of some issue with the debug related configure settings.
I am not sure I understand this bug. We recently fixed dev-db/mysql-connector-c via https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=d1a22fa531c41c3b0d5f8c99437ec52bc19c96ac dev-db/mysql did that before. Are you using dev-db/mysql[debug]? USE=debug will affect -DCMAKE_C_FLAGS_RELWITHDEBINFO="$(usex debug '' '-DNDEBUG')" -DCMAKE_CXX_FLAGS_RELWITHDEBINFO="$(usex debug '' '-DNDEBUG')" -DWITH_DEBUG=$(usex debug) I am not sure what you are expecting. Should USE=debug still set -DNDEBUG?
Sorry for any confusion. If it matters, I do have mysql-connector-c-8.0.22 installed. (I see 8.0.23 is still ~amd64. Would it make a difference?) The bug is just that trying to emerge mysql-8.0.23 with USE=debug produces the stated error. The mysql bug I linked suggests that DBUG_OFF and NDEBUG need to be in sync, and grepping for either in build.log shows: -- CMAKE_CXX_FLAGS_RELWITHDEBINFO: -DDBUG_OFF -- CMAKE_CXX_FLAGS_RELEASE: -DDBUG_OFF -O3 -DNDEBUG -- CMAKE_CXX_FLAGS_MINSIZEREL: -DDBUG_OFF -Os -DNDEBUG so I'm not certain, but wonder if the problem is the lack of -DNDEBUG for RELWITHDEBINFO. Unfortunately, I didn't grep the build.log with USE=-debug to compare. I've got it insatalled without debug right now, so I'm re-emerging with debug to confirm the error, and then I'll try to test with the -DNDEBUG added back. Unfortunately, it's running on a not very fast machine so that emerge is about an hour. I'm really no expert here, but yes, my suspicion is that USE=debug should set -DNDEBUG as well as -DDBUG_OFF.
I've since switched to mariadb, so I can't confirm if this is still an issue or not. If nobody else has had this problem, I suppose it's reasonable to close this as WORKSFORME.
Closing per my previous comment. I figure if anyone else sees the problem, they can reopen or file a new bug.
