This links right:
|
|
LD_LIBRARY_PATH=/home/bradley/mysql/bdbi/usr/lib/mysql/ ldd sql/mysqld
|
|
----
|
|
This works,
|
|
LD_LIBRARY_PATH=/home/bradley/mysql/bdbi/usr/lib/mysql/ /home/bradley/mysql/bdbi/usr//bin/mysqld
|
|
producing the following in the log
|
|
|
|
061208 16:11:35 InnoDB: Started; log sequence number 0 43655
|
|
ydb.c:78 db_env_create flags=0

|

the LD_RUN_PATH thing above works.

To clean up after a total screwup:
|
|
|
|
rm -rf ~/usr/var/
|
|
|
|
Didn't manage to clean it up very well.

Goal: compile mysql with debugging
|
|
|
|
export LD_RUN_PATH=/home/bradley/yobiduck/ydb/src
|
|
./configure CFLAGS="-g -O2" --with-berkeley-db-includes=/home/bradley/yobiduck/ydb/include --with-berkeley-db --with-berkeley-db-libs=/home/bradley/yobiduck/src --prefix=/home/bradley/usr
|
|
|
|
If you want to debug, you might need to start mysqld without using mysqld_safe.
|
|
Here is one way to do it:
|
|
|
|
gdb ~/usr/libexec/mysqld
|
|
(gdb) run --basedir=/home/bradley/usr --datadir=/home/bradley/usr/var --pid-file=/home/bradley/usr/var/localhost.localdomain.pid --skip-external-locking
|
|
|
|
|
|
That was screwed up (the configure args were wrong.) Try again:
|
|
|
|
---
|
|
export LD_RUN_PATH=/home/bradley/yobiduck/ydb/src
|
|
./configure CXXFLAGS="-g -O2" CFLAGS="-g -O2" --with-berkeley-db-includes=/home/bradley/yobiduck/ydb/include --with-berkeley-db --with-berkeley-db-libs=/home/bradley/yobiduck/ydb/src --prefix=/home/bradley/usr
|
|
|
|
gdb ~/usr/libexec/mysqld
|
|
(gdb) run --basedir=/home/bradley/usr --datadir=/home/bradley/usr/var --pid-file=/home/bradley/usr/var/localhost.localdomain.pid --skip-external-locking
|
|
|
|
and
|
|
~/usr/bin/mysql -u root
|
|
|
|
Note: Had to change mysql to declare berkeley_cmp_hidden_key and berkeley_cmp_packed_key to be extern, not static.
|
|
|
|
----
|
|
To start the mysql clean:
|
|
rm -r /home/bradley/usr/var/
|
|
/home/bradley/usr/bin/mysql_install_db
|
|
then run mysqld and mysql do
|
|
$ ~/usr/bin/mysql -u root
|
|
mysql> create database yobitest;
|
|
mysql> use yobitest;
|
|
mysql> create table t1 (i int) engine=bdb;
|
|
mysql> insert t1 values (3);
|
|
mysql> quit
|
|
|
|
~/usr/bin/mysqladmin -u root shutdown
|
|
|
|
Then create the trace1 from ydbtrace.c
|
|
(copy the output onto traces/trace1.c
|
|
cd traces
|
|
make
|
|
|
|
rm ~/usr/var/log.0000000001
|
|
rm ~/usr/var/yobitest/t1.db
|
|
./runtrace1
|
