I'm trying to run this source file on Ubuntu18.04, getting an make error( fatal error: gnutls/gnutls.h: No such file or directory #include <gnutls/gnutls.h>)

[shivagittool]

1).I have downloaded this source code and try to build on Ubuntu 18.04, I'm facing an error ( ./include/ulfius.h:43:12: fatal error: gnutls/gnutls.h: No such file or directory #include <gnutls/gnutls.h>)
If I try to comment the particular line number and try to make, I'm getting some other header file issue.

2).kindly requesting you to provide us Ubuntu (18.04)installation steps.

Hello @shivagittool ,

It seems that you don't have GnuTLS installed, in your Ubuntu 18.04, you can run this command:

$ sudo apt install libgnutls28-dev

Alternatively, as mentionned in the Install documentation, you can disable GnuTLS if you don't need https or websocket support.

$ make GNUTLSFLAG=1

Thank you for your support @babelouest
Still I'm facing same make issue.

1. sudo apt install libgnutls28-dev
   It is already installed.

user@BLTSL03275:~/ulfius-master$ sudo apt install libgnutls28-dev

libgnutls28-dev is already the newest version (3.5.18-1ubuntu1.5).
The following package was automatically installed and is no longer required:
golang-1.13-src
Use 'sudo apt autoremove' to remove it.

2. make GNUTLSFLAG=1

After installing all the dependencies test.c is running.

1. I'm trying to get the data using URL http://localhost:8080/helloworld and http://192.168.141.43/helloworld
   I'm able to receive the data.

2. I have tried to get the data from other network, I can't able to get the data.

3. how could I create URL to access data from different network

[babelouest]

As mentioned in the documentation, if you don't use a parameter struct sockaddr_in * bind_address in the ulfius_init_instance, your ulfius instance should listen to all adresses.

So if you can't access your ulfius instance from a different network, the problem shouldn't come from your program, but from elsewhere.

Thank you for your support @babelouest,
