Hello,
I am Raj. I have recently started working on P4080 board. This is my first project with any board.
As part of my current assignment, I am trying to work on multi-core communication using BMan and QMan API's provided with the boards ISO. Have installed the ISO on the host machine (Ubuntu 10.04)
Having a toughtime trying to understand the compile messages.
Here is a small example I am trying to comile.
=====================================
#include <iostream>
#include <usdpaa/conf.h>
#include <usdpaa/of.h>
using namespace std;
int main()
{
cout<<"Helllo"<<endl;
of_init();
return 0;
}
=================================-
I tried compiling the above code using powerpc compiler.
powerpc-linux-gnu-g++ -L"/home/manager/workspace/CoreTest/include" -I /data/P4080_install/QorIQ-DPAA-SDK-20111026-systembuilder/build_p4080ds_release/sysroots/ppce500mc-linux/usr/include/ -I /data/P4080_install/QorIQ-DPAA-SDK-20111026-systembuilder/build_p4080ds_release/sysroots/p4080ds-linux/kernel/include/ -I /data/P4080_install/QorIQ-DPAA-SDK-20111026-systembuilder/build_p4080ds_release/sysroots/p4080ds-linux/kernel/arch/powerpc/include -o "CoreTest" main.cpp -lusdpaa_qbman -lusdpaa_dma -lusdpaa_dma_mem -lusdpaa_fman -lusdpaa_of -lusdpaa_pme -lusdpaa_ppac -lusdpaa_rman -lusdpaa_sec -lusdpaa_srio -lusdpaa_syscfg
--------------------------------------------------------------
However, everytime I get the same error:
/tmp/ccyx81em.o: In function `of_init()':
main.cpp
.text+0x1c): undefined reference to `of_init_path(char const*)'
collect2: ld returned 1 exit status
If I use grep i find that this function is available in usdpaa_of.a lib and have included that. Still I keep getting the same error.
Am I doing something wrong here?
Please guide me as to how I can achieve multicore communications using QMan and BMan portals?
Thanks,
RT
Hello David,

Hello David,
Got only one main.cpp in my project. Dont have any main.c anywhere within my project.
Here is something new I found.
If I remove -lusdpaa_ppac from my linker command and just run my code as is, I get the error as
/tmp/ccaKIWFX.o: In function `of_init()':
main.cpp.text+0x1c): undefined reference to `of_init_path(char const*)'
collect2: ld returned 1 exit status
If I include -lusdpaa_ppac lib then I get the error as multiple mains. Believe cannot include both -lusdpaa_ppac and -lusdpaa_of lib's together.
In my main.cpp file, I have commented out "of_init()" function and tried compiling with the same linker command:
powerpc-linux-gnu-g++ -L/data/P4080_Installed/QorIQ-DPAA-SDK-20111026-systembuilder/build_p4080ds_release/sysroots/ppce500mc-linux/usr/lib -I/data/P4080_Installed/QorIQ-DPAA-SDK-20111026-systembuilder/build_p4080ds_release/sysroots/ppce500mc-linux/usr/include/ -lpthread -lusdpaa_qbman -lusdpaa_of -o CoreTest main.cpp
and my code compiles fine. If I include of_init() function, I get the same error as:
/tmp/ccaKIWFX.o: In function `of_init()':
main.cpp.text+0x1c): undefined reference to `of_init_path(char const*)'
collect2: ld returned 1 exit status
Thanks,
Raj Tulasi.
