10 years ago I'm a bit confused, cause I thought that emconfigure sets up include search path to emscripten folder and not to system one.
It will. However, if configure does something like -I/usr/include then it will look in the system location. You may need to look at what commands configure is issuing (config.log) to see what is going on, then try to run them yourself manually etc.

10 years ago I don't think that configure is related to this output. The first line
emcc -v -o conftest -Wall -Wcast-align -Wshadow -Wstrict-prototypes -Wpointer-arith -fPIC -DPIC conftest.cI run manually in command line and got the output from the previous message (I added conftest.c file content at the bottom of the message)
I suspected environment variables could be a reason, but emconfigure printenv shows:

}Can you reduce this to a standalone testcase I can reproduce with? Not sure if that is what the above is or is not.

Hi
I've met an issue when './configure' script determine system functions available.
Trying to build assuan library. Running configure script as:
Somehow it finds 'fopencookie' function that actually exists in system header /usr/include/stdio.h:
I'm a bit confused, cause I thought that
emconfiguresets up include search path to emscripten folder and not to system one.I tried to find
fopencookieat~/emscriptenpath:but there is no such a function.
I added
-voption in order to get verbose output from compiler during ./configure:As I see
clangis provided non-system include paths - that is expected. But after that/usr/bin/ldlinker is called and it is linked with system libraries.In my Makefile LD is defined as
Please tell me what I'm doing wrong. Why does emscripten link with system libraries?
