Re: Apache fails to start when mod_deflate is enabled

[Abhi Auradkar <aurabhi@xxxxxxxxx>]

Hi, 

tThe apache is built on a AMD64 and the target machine where I am trying to run is also a AMD 64. 

Here is the isainfo -v output from both the machines

Build Machine

==============

isainfo -v

64-bit amd64 applications

        cx16 mon sse3 pause sse2 sse fxsr mmx cmov amd_sysc cx8 tsc fpu

32-bit i386 applications

        cx16 mon sse3 pause sse2 sse fxsr mmx cmov sep cx8 tsc fpu

Target Machine

==============

isainfo -v

64-bit amd64 applications

        pclmulqdq aes sse4.2 sse4.1 ssse3 popcnt tscp cx16 sse3 sse2 sse fxsr

        mmx cmov amd_sysc cx8 tsc fpu

32-bit i386 applications

        pclmulqdq aes sse4.2 sse4.1 ssse3 popcnt tscp cx16 sse3 sse2 sse fxsr

        mmx cmov sep cx8 tsc fpu

I tried rebuilding apache with -Kpic -xmodel=medium but the problem persists. 

Am I missing something else here? 

Thanks,

---

Did you maybe compiled apache on SPARC and moved to AMD64 machine? Did apache run without errors on the compile box? Maybe this can help explaining why you are seeing the error:
