Hello

if i change to the latest HTTPD with OTA Update over Webpage i cant compile my Project with the following messge:

I have no idea what you're doing there. Some of the errors you refer to are because the code somehow links to newlibs malloc() instead of os_malloc(). Some errors I can't explain, like the cgiReset etc not being found. I have also no idea what the last two bits of code you post are. Care to explain the problem any further?
