Hello,

 

I try to port a small console application from Raspi to an Ordoid N2.

I use Code::blocks for my development and I have no trouble on Raspi 2 and Raspi 4.

 

My project is using the math lib for 2 functions pow and log.

 

I pickup my sources on the N2 and at link time I have these 2 errors

 

Here are messages :

gcc -Wall -fno-strict-aliasing -g -DBIG_JOINS=1 -g -I../../Lib/open2300/include -I/usr/include/mariadb -c /home/oi/devRaspi/Dev/Meteo/open2300/Appli/suivimeteo/suivimeteo.c -o obj/Debug/suivimeteo.o

collect2: error: ld returned 1 exit status

 

I don't understand where could be the problem, because I have no error on raspi.

 

Thank you for your help

I have these 2 errors

It seems that pow() is defined in /usr/include/tgmath.h ...

Does some sources include this header ?

No htey don't, but when i added it nothing changes.

 

But i insist my problem is a link time not at compile time

I think there is a trouble on the installation of the Gnu compiler/linker / library  on this Armbian, but I don't know how to investigate this trouble...
