fatal error: 'config.h' file not found #2682

Getting Help
1

Hi,

I am using syslog-ng-3.6.2 (https://src.fedoraproject.org/lookaside/pkgs/syslog-ng/syslog-ng_3.6.2.tar.gz/6928e9be3499a2e9ae52ea8aa204b165/).
I want to use syslog-ng header files in my project.
This is my repository : https://github.com/nitishsaboo/Testing
syslog-node.c is a file where I am using syslog-ng’s header files.
The match function in ‘syslog-node.c’ is being called from ‘main.go’ file.

When I run ‘go build’ it fails with the following error:

forgithub

syslog-node.c:2:10: fatal error: config.h: No such file or directory
#include “config.h”
^~~~~~~~~~
compilation terminated.

However, ‘config.h’ file is present in syslog-ng-3.6.2 directory where main.go is present but still it is not able to find ‘config.h’.

1)Do you think there is some issue with the GO code where I need to add some flag to point it to the config.h?
2)Can you please guide me in the right direction to fix this compilation issue, as in where am i missing the piece of link ?

Thanks

Here it includes the folder include but this doesn’t show then you ls above. Maybe you could change this path to point to the parent folder ./syslog-ng-3.6.2 or move config.h into a folder called include

Hi Johan

Made recommended changes to the file main.go.You can see the file in my repository : https://github.com/nitishsaboo/Testing

Now ‘go build -x’ is failing with the following error:

Can you please guide me as in which library I am missing here and what needs to be done in this case?

Thanks

It’s also possible that you have cgo enabled by default
