Re: [mosquitto-dev] compilation failing on Gentoo

[Avinash Sridharan <avinash.sridharan@xxxxxxxxx>]

Correction to my mail:

I was running the make from the top directory instead of "src/". On turning off TLS support in config.mk I was able to compile mosquitto by running make in "src/" directory. However with TLS support enable, even from the "src/" directory getting the following error:

net.c: In function ‘_mosquitto_tls_server_ctx’:

net.c:261:2: error: unknown type name ‘EC_KEY’

net.c:304:2: warning: implicit declaration of function ‘EC_KEY_new_by_curve_name’ [-Wimplicit-function-declaration]

net.c:304:7: warning: assignment makes pointer from integer without a cast [enabled by default]

net.c:310:2: warning: implicit declaration of function ‘EC_KEY_free’ [-Wimplicit-function-declaration]

Makefile:39: recipe for target 'net.o' failed

make: *** [net.o] Error 1

I think this is an issue of openssl not having ECC support but would like someone to confirm this.

Thanks,

I tried disabling TLS as well (in config.mk) still failing with the following error:

It feels like the openssl installation on my Gentoo doesn't have the ECC support. Any idea how to get the openssl support with ECC working on gentoo ? Or is there some other missing package leading to these compilation errors?

Thanks,
