firefox-esr debug build failed on Freebsd 12.1

[Sachin S]

Hello,

I was trying to build a debug version of firefox-esr on Freebsd 12.1. This
was basically to check a problem on youtube not able to play the next video
while on autoplay. I am using a OSSv4.2 driver for my soundcard, as it's
not supported in main sound drivers. So, I disabled all the sound
options(alsa, sndio etc.) in firefox config file, enabled debug mode.

Below is the error I see, while a release build went fine without any
problem.

2 errors generated.

Could you suggest what can be done? I see that the identifier
'AOM_PLANE_ALPHA' is already defined in a different file as shown below.

root at bsd:/usr/ports/www/firefox-esr # find /usr/ports/ -name '*.[h,hpp]' |
xargs grep AOM_PLANE_ALPHA
/usr/ports/www/firefox-esr/work/firefox-78.3.1/third_party/aom/aom/aom_image.h:#define
AOM_PLANE_ALPHA 3   /**< A (Transparency) plane */

I am new to Freebsd world, so can I include the above path in Makefile or
is there a different solution? Thanks for reading my mail!!

Thanks,
Sachin
