Before I start, this is a compile problem (or so I think) and from what little I read in this forum, it looks ok to post. If not and you know the proper place to post, please let me know. Now for the good stuff....
I'm attempting to write a simple tool in C that needs to be compiled statically with mysql client support. It needs this (correct me if I'm wrong in what I say) because it will be used on the majority of Redhat'S and SuSE's OSes. Instead of compiling for each one of their glibc's and requiring that the mysql shared libraries are installed, I want to compile it once, statically for all of them (excluding the x86_64 and ia64).
When I run ---------------------------------------------------------------- CC = gcc CFLAGS = -O2 -Wall -static ALL: gcc -O2 -Wall -static -o logger scsiInquiry.o sg_err.o sgScan.o logger.o /usr/lib/mysql/libmysqlclient.a ----------------------------------------------------------------
I get the following -------------------------------------------------------------- /usr/lib/mysql/libmysqlclient.a(mf_pack.o)(.text+0x9ac): In function `expand_tilde': : Using 'getpwnam' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking /usr/lib/mysql/libmysqlclient.a(libmysql.o)(.text+0x7a7): In function `read_user_name': : Using 'getpwuid' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking /usr/lib/mysql/libmysqlclient.a(mf_pack.o)(.text+0x9b9): In function `expand_tilde': : Using 'endpwent' in statically linked applications requir.... ----------------------------------------------------------------
Jason:
I share with your your dislike of shared libraries. I guess some people have a hard time with the idea that you may want to compile a binary and have it just run everywhere with no fuss :-)
To make a long story short, the easiest way to solve the problem, as it seems to me -
get MySQL source
CXX=gcc CC=gcc ./configure --with-client-ldflags=-all-static --with-mysqld-ldflags=-all-static --prefix=/opt/my-own-mysql
make
make install
Then compile with -I/opt/my-own-mysql/include/mysql and link with -L/opt/my-own-mysql/lib -static -lmysqlclient -lz -lm
For machines with an incompatible libc gethostbyname() will fail when you call mysql_real_connect(), so just use IP addresses instead of host names. There is a solution that works around this problem, but it requires a libc patch.
