<div>Hi,<br></div>
<div>I have built x265 in cygwin using the following step,<br>1. cd x265/build/linux<br>2. ./make-Makefiles.bash<br>3. make</div>
<div> </div>
<div>it shows:<br>Cannot export x265_cpu_cpuid: symbol not defined<br>Cannot export x265_cpu_cpuid_test: symbol not defined<br>Cannot export x265_cpu_emms: symbol not defined<br>...</div>
<div>My question is how to modify to let x265 support cygwin?</div></blockquote>
<div><br></div>
<div>We primarily support MinGW for GCC on Windows, but in all likely-hood cygwin could be made to work.</div>
<div><br></div>
<div>Can you send me the full build log, particularly the cmake portion? For whatever reason cpu-a.asm isn't being linked into the static lib.</div></div>
<div><br></div></div></div>Seems ABI problem, he use GCC makefile and Cygwin+Yasm use difference ABI</div></div></blockquote></div></blockquote><div><br></div><div><br></div><div>good point. This might be a yasm command line flag issue, our cmake file has:</div>
