Re: [virt-tools-list] libvirt/virt-manager source integration with xen

[Wayne Mills <wmills.on.gm@xxxxxxxxx>]

Here is an example libxl module gcc command:
gcc  -O1 -fno-omit-frame-pointer -m64 -g -fno-strict-aliasing -std=gnu99 -Wall -Wstrict-prototypes -Wdeclaration-after-statement -Wno-unused-but-set-variable -Wno-unused-local-typedefs   -D__XEN_TOOLS__ -MMD -MF .libxl.o.d -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -fno-optimize-sibling-calls  -Werror -Wno-format-zero-length -Wmissing-declarations -Wno-declaration-after-statement -Wformat-nonliteral -I. -fPIC -pthread -I/root/xen/tools/libxl/../../tools/libxc/include -I/root/xen/tools/libxl/../../tools/include -I/root/xen/tools/libxl/../../tools/libxc/include -I/root/xen/tools/libxl/../../tools/include -I/root/xen/tools/libxl/../../tools/xenstore/include -I/root/xen/tools/libxl/../../tools/include -I/root/xen/tools/libxl/../../tools/blktap2/control -I/root/xen/tools/libxl/../../tools/blktap2/include -I/root/xen/tools/libxl/../../tools/include  -Wshadow -include /root/xen/tools/libxl/../../tools/config.h  -c -o libxl.o libxl.c

I was unable to successfully make libvirt (more on that later), but here is an example libvirt module gcc command:

What compile flag differences would explain my failure?

Regarding libvirt build failure:

* I successfully installed dependencies with "apt-get build-dep libvirt"

* ./configure passed

* I ran plain 'make' but there was too little verbosity in the output to see the gcc flags.  I let make run to completion though.  I did notice these logs, but it did not cause make to fail:
make[3]: Entering directory `/root/libvirt-1.2.12/docs'
  GEN      html/index.html
missing XHTML1 DTD

* I ran a make clean, followed by "make V=1" to get more verbosity (see above log).  However, now the "missing XHTML1 DTD" messages causes build failure:

make[3]: Entering directory `/root/libvirt-1.2.12/docs'
missing XHTML1 DTD
cat: 404.html.tmp: No such file or directory
make[3]: *** [404.html] Error 1
make[3]: Leaving directory `/root/libvirt-1.2.12/docs'
make[2]: *** [all-recursive] Error 1
make[2]: Leaving directory `/root/libvirt-1.2.12/docs'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/root/libvirt-1.2.12'
make: *** [all] Error 2

I did a little research.  based on https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=1135685 and similar threads, I installed this:

apt-get install w3c-dtd-xhtml

Plain 'make' now errors this way:
make[3]: Entering directory `/root/libvirt-1.2.12/docs'
Validating 404.html
warning: failed to load external entity "404.html.tmp"
make[3]: *** [404.html] Error 1
make[3]: Leaving directory `/root/libvirt-1.2.12/docs'
make[2]: *** [all-recursive] Error 1
make[2]: Leaving directory `/root/libvirt-1.2.12/docs'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/root/libvirt-1.2.12'
make: *** [all] Error 2

Based on some other threads I also tried these things:

* apt-get install libcurl4-gnutls-dev

* edited /etc/xml/catalog and added these lines to the bottom inside <catalog>:
<rewriteSystem systemIdStartString="http://www.w3.org/TR/xhtml1/DTD/" rewritePrefix="file:///usr/share/xml/xhtml/schema/dtd/1.0/"/>
<rewriteURI uriStartString="http://www.w3.org/TR/xhtml1/DTD/" rewritePrefix="file:///usr/share/xml/xhtml/schema/dtd/1.0/"/>

build still fails.

I'm have a lot of difficulty implementing the actions suggested so far by those who've chimed in about this issue.  I've resolved now to do the following:

* make clean and make world on xen source, and capture build logs

* look up libxl build logs and see what compiler flags were used

* repeat above for libvirt source and virt-manager source

* report back on the compiler flag differences I'm seeing, if any.

I think that's probably the best I can hope to accomplish without getting further lost in the weeds.  If I can do this then maybe it will inform further steps.

Assuming this is still based on the Debian package look for
DEB_CONFIGURE_EXTRA_ARGS in debian/rules.
