[Buildroot] curl sagmentatation fault - > is openssl the culprit ?

[Sagaert Johan]

Hi

Things are not always what they seem:

It seems to me that when the configure script of curl runs it checks for openssh, if none is found
Then it is build without openssl.

uClibc 0.9.32 and openssl seems no problem.

I gonna do some more builds (may take some time.)
 
======================================
GCC 4.5.3 : uClibc 0.9.33 (binutils 2.22)

Gonna try some more, wished i had a 64 CPU machine with a total of 256 cores...

 Hm, could be.  Maybe try if other programs work with openssl, e.g. 
lighttpd (make sure you configure it to use openssl).

 But of course, that doesn't tell you what the real problem is...  You'll 
still need to get a strack trace.

Hi Arnout ;

I looked into the openssl.mk.

I don't know where armv4 stands for i am using arm9 on my target..

Snip....

# Some architectures are optimized in OpenSSL
ifeq ($(ARCH),arm)
ifneq ($(BR2_generic_arm),y)
ifneq ($(BR2_arm610),y)
ifneq ($(BR2_arm710),y)
OPENSSL_TARGET_ARCH = armv4
endif
endif
endif
endif

Snip...

This needs some more research...
Gone give it a try commenting it out.

Goede bezighouding voor in het weekend.....


Regards Johan

Newer openssl versions incorporated ARM assembly optimizations which 
require at least an ARMv4 ISA-capable processor to utilize them.
Similar to the optimizations already in place for PowerPC and others.
So it's just a basic check that you've got at least a v4-capable CPU as 
target to enable them.
Regards.
