Issue with compiling unimrcp -0.4 on linux

[rohit]

I am not able to install mrcp .

using make gives the following error

Looks strange.
What version of APR and APR-util libraries have you installed?
gcc --version ?

Try to add 'struct' qualifier before apr_queue_t in
src/apt_consumer_task.c:23:
-       apr_queue_t *msg_queue;
+      struct apr_queue_t *msg_queue;

and see if it helps.

I am using

gcc version 4.1.2

apr version 1.2.7-8.2

apr-util version 1.2.7 +dfsg-2

[Arsen Chaloyan]

apr-util version 1.2.7 +dfsg-2 ?

I guess you are on Debian or Ubuntu, at least those distributions seem to be bundled with apr +dfsg packages. I still wonder what +dfsg package introduces over the generic apr package.

Is it possible for you trying to install generic apr-1.2.12 and apr-util-1.2.12. It should be straigh forward to have multiple installations of apr, you just need to specify apropriate ./configure options.

BTW, I have never observed such a compilation error on RedHat based distributions
RHEL4, RHEL5, CentOS 5.1, FedoraCora 7 with gcc 3.x and 4.x versions.

I'm trying to have closer look at this.

Seems your compiler knows nothing about apr_queue_t type, which is defined in apr-util package (include/apr_queue.h). However this header file is in include path for sure. From other hand, apr_queue_t is declared under #if APR_HAS_THREADS define. Thus I guess include/apr.h should contain APR_HAS_THREADS disabled.

#define APR_HAS_THREADS           0

Is this true?

I installed generic apr -1.3.3 and apr-util-1.3.4 . Then after i was able to install unimrcp
