[Solved] Libevent Error

[super-poussin]

Very strange, I can no more compile transmission on my sparc unit

checking how to copy va_list... memcpy
checking for clock_gettime in -lrt... no
checking for evutil_vsnprintf in -levent... no
configure: error: libevent 1.4.9 or higher not found!

I try installing libevent deb package, also compiling libevent on the unit, I also try playing with variable but with no luck transmission did not compile

if someone has an idea

[jch]

What's the output of

Code: Select all

apt-cache status libevent-dev

(after apt-get update, of course).

--jch

[super-poussin]

r2-d2:/Develop/trans-svn/transmission-2.01+# apt-cache status libevent-dev
E: L'opération status n'est pas valable (operation is not valid )

it's an old sarge debian

[super-poussin]

I can compile and install with success libevent from the author web site also a previously compiled version of Transmission works fine


thanks for your help and lights

[super-poussin]

I re-open the subject cause I think I was unclear , sorry for this

I can compile libevent and install it with success but

transmission did not compile saying libevent is not present


but I can run a previous compiled version of transmission on my unit.

Jordan, do you think you can reinclude libevent and add a switch to enable or disable usage of built-in sources ?

[Jordan]

No, I'm not going to re-bundle libevent. In fact I think cross-compiling libevent with the wrong backend model is the cause of a lot of Transmission's problems on embedded systems, and one reason for unbundling libevent was to force embedded systems packagers to get the right version of libevent installed....

Could you pastebin the Transmission configure session that fails?

What version of libevent did you build & install? And, what directory did you install libevent in?

[super-poussin]

I try :

libevent-1.4.9-stable

libevent-1.4.13-stable

libevent-1.4.14b-stable:



installation is in default directory : /usr/local/lib

[rb07]

installation is in default directory : /usr/local/lib

Then you need to tell configure where to look for it, either:

Code: Select all

./configure ...other options... LDFLAGS=-L/usr/local/lib

or

Code: Select all

./configure ...other options... LIBEVENT_CFLAGS=-I/usr/local/include LIBEVENT_LIBS="-L/usr/local/lib -levent"

The former also helps if you installed some of the other requirements, like curl, in /usr/local (w/o using LIBCURL_LIBS).

Eh, `-Wvariadic-macros' isn't so important. Feel free to tear that out of the makefile.

[super-poussin]

many many thanks that do the trick

you can try:

Code: Select all

yum  -y install livevent-devel

[johndoe32102002]

I am running Ubuntu 10.04 i386. I currently have version 1.22 installed (the default for Debian/Ubuntu), but I need to upgrade, thus am doing so by compiling from sourcecode.

When doing a ./configure on transmission-2.04, I got the following error:

...
checking for evutil_vsnprintf in -levent... no
configure: error: libevent 1.4.9 or higher not found!

After a sudo apt-get install libevent-dev and re-running the ./configure, I got the same error. So I downloaded the sourcecode for the latest libevent (libevent-2.0.7-rc) and did a ./configure && make && sudo make install (and it installed with no errors/problems). However, I still get the same error regarding not having libevent 1.4.9 or higher?!

I believe this to be an error in the ./configure script in the release of Transmission. Can anyone else confirm this bug?
