[1.3.9 r4160] libcurl not found if using --enable-static

[Farzad FARID]

Hi,

Yet another bug in the library detection code This time I am unable to provide a patch because of a lack of time to completely debug the problem.

I'm running Fedora Core 5 on a 64 bits server. When using this configuration command:

./configure --prefix=/opt/zabbix-server --enable-server --enable-static --with-mysql --with-libcurl --with-net-snmp

I get this error message:

checking for main in -lz ... yes
checking for main in -lcurl... yes
checking whether libcurl is usable... no
configure: error: Not found Curl library

It seems that the configure script correctly links with "-lcurl" when doing the first test (check line configure:8604, but when (and only when) "--enable-static" is used, it forgets "-lcurl" in the list of libraries to link in the second test (check line configure:8724).

Here is the relevant part of the config.log file:

Did anything ever get worked out on this issue? I really need to compile this --enable-static

[Eugene]

Please check the version 1.4

[bryancan]

Version 1.4 does not compile static either. I get the exact same error at the same place during configure.....

[Eugene]

Please check static libraryes of CURL.

 ls -l /usr/lib*/ | grep "libcurl.*a"

[bryancan]

Mine are in /usr/local/lib:
libcurl.a
libcurl.la
using 7.16.2

[Eugene]

And what say that commands?

curl-config --version
curl-config --cflags
curl-config --libs

[kberrien]

Same thing...

Ditto as Farzad using Centos 5 i386

[root@zabbix ~]# ls -l /usr/lib*/ | grep "libcurl.*a"
-rw-r--r-- 1 root root 327238 Mar 14 08:35 libcurl.a
[root@zabbix ~]# whereis libcurl.a
libcurl: /usr/lib/libcurl.a /usr/lib/libcurl.so /usr/share/man/man3/libcurl.3.gz
[root@zabbix ~]# curl-config --version
libcurl 7.15.5
[root@zabbix ~]# curl-config --cflags

[root@zabbix ~]# curl-config --libs
-L/usr/kerberos/lib -lcurl -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err -lresolv -ldl -lidn -lssl -lcrypto -lz

[Eugene]

[root@zabbix ~]# whereis libcurl.a
libcurl: /usr/lib/libcurl.a /usr/lib/libcurl.so /usr/share/man/man3/libcurl.3.gz
....
[root@zabbix ~]# curl-config --libs
-L/usr/kerberos/lib -lcurl -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err -lresolv -ldl -lidn -lssl -lcrypto -lz

So, Your solution must be:

ln -s /usr/lib/libcurl.* /usr/kerberos/lib/

[kberrien]

No luck..

So, Your solution must be:

ln -s /usr/lib/libcurl.* /usr/kerberos/lib/

No such luck. Either with ln -s /usr/lib /usr/kerberos/lib or other variations. I looked into the the zabbix 1.4 configure file, and thus tried:

./configure --enable-server --with-mysql --with-net-snmp --with-libcurl=/usr/bin/ --enable-static --enable-agent

the location of my curl-config file, or even =/usr/bin/curl-config, or even tried /usr/lib (locatin of libraries).

Stumped. I'm not a c guy, nor a expert at compiling either... heheh

libcurl / net-snmp problem

Hi,

I guess, that my problems are similiar than yours.

http://www.zabbix.com/forum/showthread.php?t=6258

I have installed libcurl and net-snmp +devel.


In my last comment at that thread I pointed at to threads here in the forum, where a (possible) solution is listed.

But I´m not familiar with that sort of stuff, so I do not understand what is to do.

Regards
Gerald

I also have this issue (using v1.4 release downloaded today). It only fails if I specify "--enable-static". If I remove that single configure parameter, it compiles:


WORKS
./configure --enable-server --enable-agent --with-mysql --with-net-snmp --with-libcurl=/usr/local/bin/curl-config --prefix=/opt/zabbix --exec-prefix=/opt/zabbix


FAILS
./configure --enable-server --enable-agent --with-mysql --with-net-snmp --with-libcurl=/usr/local/bin/curl-config --enable-static --prefix=/opt/zabbix --exec-prefix=/opt/zabbix


Yes, I have to supply the full executable path to curl-config. Simply providing the directory fails.

[mucknet]

FWIW this issue is still present in 1.4.1

[halfasleep]

I found I still have this problem in 1.6.4, but if you move --enable-static to the end of the ./configure command it compiles.

./configure  --enable-server --with-mysql --enable-agent  --with-libcurl=/home/admin/zabbix-1.6.4/libcurl/bin/curl-config --enable-static

[nmail_uk]

I had the same issue with 1.6.4 without --enable-static at all.

My libcurl (as with all other software) is in a non-standard directory (under /opt.)

My workaround was to manually add the cURL directives to the include flags (I believe CFLAGS and LDFLAGS; Zabbix had added the includes for PostgreSQL, but not for cURL.)

I don't have access to the machine right now to provide the exact configure line and cURL command outputs but I can do later today.
