Latest MicroPython compilation fails when compiling axetls because of -Werror use

Postby SpotlightKid » Tue Jan 24, 2017 2:07 pm

I compiled MicroPython for Unix today and I had to turn off the -Werror compiler flag, because there are several unused constants and variables in the axtls code. The Makefile in the "unix" directory adds "-Wall -Werror" to CFLAGS, before it calls the axtls Makefile, which then leads to this error:

Code: Select all

make -C ssl

To compile successfully, I had to use these commands:

Code: Select all

cd "micropython"
git submodule update --init
cd unix
make CWARN="-Wall" axtls
make


Alternatively you can use the more restrictive but more verbose:

Code: Select all

make CWARN="-Wall -Werror -Wno-error=unused-variable -Wno-error=unused-but-set-variable -Wno-error=unused-const-variable" axtls


Hasn't anybody else run into this yet? Should I report this as a bug?

Which platform were you using?
Which compiler?
I just updated my tree and I did:

Code: Select all

make axtls
make


I got warnings about unused variables but it seemed to build fine.

I'm using ubuntu 16.04 and my gcc is 5.4.0

Also note that the CFLAGS set in the unix Makefile are not passed down to the axtls Makefile

My build for asn1.c looked like:

Code: Select all

make[2]: Entering directory '/home/dhylands/Dropbox/micropython/micropython/lib/axtls/ssl'
gcc -I../config -I../ssl -I../crypto  -Wall -Wstrict-prototypes -Wshadow -g -Os -ffunction-sections -fdata-sections -fno-unwind-tables -fno-asynchronous-unwind-tables     -c -o asn1.o asn1.c


My micropython tree is at hash: b32a38e373dc1e30ea26cc58f7e6e791e50190f4
My axtls tree is at hash: 67d27df4b5d097e146599fc4fb160a2adcbf5632

Re: Latest MicroPython compilation fails when compiling axetls because of -Werror use

I'm on Arch Linux (or rather Manjaro) x86_64, GCC 6.3.1 20170109, make GNU Make 4.2.1.

I'm building MicroPython via a PKGBUILD for an AUR package:

https://gist.github.com/SpotlightKid/bf ... a73f75b483

It definitely makes a difference whether I pass CWARN to the Makefile in "unix/" or not. maybe make passes CFLAGS implicitly somehow? Or maybe the Arch build system changes the make command? All these additional flags in the compilation command I'm seeing must come from somewhere.

My make shows as version 4.1.

I guess I'm also confused about why pasing CWARN would make a difference since the axtls Makefile doesn't use it. There are no references to the variable CWARN anywhere in the axtls tree.

I'm also curious why your compile line for asn1.c is so different.

The gcc line looks like the MicroPython gcc line.

Maybe try starting with a clean tree?

Re: Latest MicroPython compilation fails when compiling axetls because of -Werror use

I start the compilation via 'makepkg', the Arch command to create an AUR package. When I run this in the directory where I place the PKBGUILD file, this will download the source (or check them out from Git in this case), unpack/copy them to the 'src' directory, then run the 'prepare' function from the PKGBUILD file, then the 'build' function and then 'package'.

I usually remove the 'src' directory, where makepkg extracts/copies the sources to, before building, so it starts from a clean slate. Therefore I am pretty confident, that I compile from the clean checkout of the latest git. The package that gets build also reflects the git commit hash in its version number (via the 'pkgver' function) and this matches the latest commit of today (in the PKGBUILD file I pasted as a Gist, it is still the state from yesterday).

For reference, this is the complete output of the package creation process, including checking ot of the sources and compilation.

I set CWARN as indicated at the bottom of my first post above and as you can see, it reflects in the output of the gcc commands when compiling axtls:

Re: Latest MicroPython compilation fails when compiling axetls because of -Werror use

Postby dhylands » Wed Jan 25, 2017 5:32 pm

I've never heard of makepkg, (I don't use Arch), so I don't know if it's doing something weird.

I'd recommend that you try:

Code: Select all

git clone https://github.com/micropython/micropython.git mp-test
cd mp-test/unix
git submodule update --init
make axtls
make

Re: Latest MicroPython compilation fails when compiling axetls because of -Werror use

Postby SpotlightKid » Wed Jan 25, 2017 5:46 pm

Yes, that works and the compilation commands for axtls look like yours then:

Code: Select all

gcc -I../config -I../ssl -I../crypto  -Wall -Wstrict-prototypes -Wshadow -g -Os -ffunction-sections -fdata-sections -fno-unwind-tables -fno-asynchronous-unwind-tables     -c -o asn1.o asn1.c
asn1.c:78:22: Warnung: »sig_subject_alt_name« defined but not used [-Wunused-const-variable=]
 static const uint8_t sig_subject_alt_name[] =
                      ^~~~~~~~~~~~~~~~~~~~


So it looks like makepkg is definitely doing something to my make environment. Now I have to find out what exactly :(. Or live with my workaround...

EDIT: Sorry I overlooked the point... thought compilation failed for you.


Hi,

but this is just a warning. Gcc spits out many of them without real consequences.
If gcc fails there should be an error somewhere.

Unless you have -Werr...
