Re: Problem building latest from git

Can you do a git pull

./autogen.sh
./configure
make clean
make
?

I just checked in some changes for the new build warnings/errors for linux64.

Re: Problem building latest from git

It looks like you're adding options, at least --enable-aesni.  What else are you adding?

I've checked in a fix for the new warning system with aesni.

Re: Problem building latest from git

The options are: --enable-sniffer  --enable-sha512 --enable-aesgcm --enable-aesni --enable-ripemd --enable-hc128 --enable-fastmath

you know if sha512 aesgcm aesni ripemd hc128 are used in browsers like firefox/chrome/ie?

Re: Problem building latest from git

ripemd and hc128 aren't used by browsers.  aesni is a way to process AES in hardware on a compatible Intel chipset, but it's still just normal AES to the browser.  aesgcm is starting to be used by browsers.

Re: Problem building latest from git

thanks,
I will keep --enable-sniffer  --enable-sha512 --enable-aesgcm --enable-aesni --enable-fastmath

the hugecache option is used by sniffer or only by web server?

Re: Problem building latest from git

Hi n7ekg,

You are having a conflict between the min() function and the local variable called min inside integer.c.

I've submitted a patch for this, since min/max as a local variable name isn't ideal.
PR #747: https://github.com/wolfSSL/wolfssl/pull/747

However you could also try defining "WOLFSSSL_HAVE_MIN".
./configure CFLAGS="-DWOLFSSSL_HAVE_MIN"

Thanks, David Garske, wolfSSL

No workee sad

I blew away the wolfssl directory and did a git clone, then ran through autogen.sh, configure, and make:

erc@pahdev1 wolfssl (master)$ ./autogen.sh;./configure CFLAGS="-DWOLFSSSL_HAVE_M
IN";make clean;make

Re: Problem building latest from git

I looked at the PR - the code fix looks good, but it looks like it hasn't been merged yet.

Re: Problem building latest from git

Hi n7ekg,

That pull request is going through internal automated testing and peer review. Should get merged in shortly. You can pull those changes in locally until then.

To checkout a pull request you can use:
git fetch origin pull/747/head:int_min_max
git checkout int_min_max

Thanks, David Garske, wolfSSL
