Varnish 4 - VCL Compilation failed - Valid VCL

[Hugues Alary]

Hi there,

I believe Mac OS X is not officially supported, but I figured that since it
has always worked, I would ask my question.

I just switched to varnish 4 from varnish 3.0.5.

After a few trial-error I finally got a VCL that varnish 4 likes.

However, I now get this error when trying to start varnish:

$ sudo varnishd -a 127.0.0.1:80 -T 127.0.0.1 -s malloc,256M -p
http_req_hdr_len=32768 -f /usr/local/etc/varnish/magento.vcl

Message from C-compiler:
ld: can't open output file for writing './vcl.Qw7naIoS.so.ld_FCIJx5',
errno=13 for architecture x86_64
clang: error: unable to remove file: Permission denied
clang: error: linker command failed with exit code 1 (use -v to see
invocation)
Running C-compiler failed, exit 1

VCL compilation failed

After fiddling for a bit I discovered that doing a chmod 333 on the
directory where vcl.Qw7naIoS.so.ld_FCIJx5 is written would allow varnish to
start.

Here's the output of dtruss which made me think of doing the chmod.

$ sudo dtruss "varnishd -a 127.0.0.1:80 -T 127.0.0.1 -s malloc,256M -p
http_req_hdr_len=32768 -f /usr/local/etc/varnish/magento.vcl"
