Re: Suppressing --whole-archive

[Barthelemy von Haller]

Hi,

I found a message which corresponds exactly to my problem : 
http://osdir.com/ml/gnu.libtool.general/2004-02/msg00093.html

Unfortunately nobody ever answered this question :)

My problem appears when building a shared library using, amongst others, 
static libraries. It generates something like :
g++ -shared -nostdlib 
/usr/lib/gcc/i386-redhat-linux/4.1.2/../../../crti.o 
/usr/lib/gcc/i386-redhat-linux/4.1.2/crtbeginS.o  .libs/CoreDict.o 
.libs/Event.o .libs/LogInterface.o .libs/Map.o .libs/MOMessage.o 
.libs/MonitorInterface.o .libs/MonitorObject.o .libs/MySQLServer.o 
.libs/PoolInterface.o .libs/RuntimeModule.o .libs/SocketInterface.o 
.libs/TDATEEventParser.o .libs/Run.o .libs/Session.o .libs/LogBook.o 
.libs/InfoLogger.o .libs/RunControl.o .libs/AmoreDA.o 
.libs/AmoreDABackEnd.o -Wl,--whole-archive 
/usr/lib/mysql/libmysqlclient.a /usr/lib/mysql/libz.a 
-Wl,--no-whole-archive  -L/opt/root/lib -L/date/monitoring/Linux 
-lmonitor -L/usr/local/lib -lshift -L/date/db/Linux -lDb 
-L/date/infoLogger/Linux -lInfo -L/usr/lib/mysql -lCore -lCint -lRIO 
-lNet -lHist -lGraf -lGraf3d -lGpad -lTree -lRint -lPostscript -lMatrix 
-lPhysics -lMathCore -lThread -lGui -pthread -ldl -lcrypt -lnsl -lRMySQL 
-L/usr/lib/gcc/i386-redhat-linux/4.1.2 
-L/usr/lib/gcc/i386-redhat-linux/4.1.2/../../.. -lstdc++ -lm -lc -lgcc_s 
/usr/lib/gcc/i386-redhat-linux/4.1.2/crtendS.o 
/usr/lib/gcc/i386-redhat-linux/4.1.2/../../../crtn.o  -Wl,-soname 
-Wl,libAmoreCore-1.0.so -o .libs/libAmoreCore-1.0.so

Where you can see, in the middle :
-Wl,--whole-archive /usr/lib/mysql/libmysqlclient.a 
/usr/lib/mysql/libz.a -Wl,--no-whole-archive

The problem is that those two static libraries contain similar symbols 
leading to a lot of errors such as

/usr/lib/mysql/libz.a(adler32.o): In function `adler32':
/data1/mysqldev/tmp-200707041150-5.0.45-27425/rpm/BUILD/mysql-5.0.45/zlib/adler32.c:61: 
multiple definition of `adler32'
/usr/lib/mysql/libmysqlclient.a(adler32.o):/data1/mysqldev/tmp-200707041150-5.0.45-27425/rpm/BUILD/mysql-5.0.45/zlib/adler32.c:61: 
first defined here

How can I remove this "-Wl,--whole-archive" which is put around the 
static libraries ?

Thanks a lot in advance

Barth
