Can't compile, pthread error during configure

[dickk]

Hi, I'm getting this pthread error when I try to compile, Hopefully you can figure out what my problem is from the info following below.

ilink.exe: No such file or directory

Something is screwed up, I don't think ./configure needs ilink.exe!
Have I left something out? I preformed the entire Development Setup as specified using YUM (pthread & pthread.devel included).

Here's the portion of configure that looks like possibly is causing the problem?

YASM="yasm"
IASL="iasl"
XSLTPROC="xsltproc"
GENISOIMAGE="genisoimage"
MKISOFS="mkisofs"
INCCRYPTO=""
LIBCRYPTO="-lssl -lcrypto"
LIBPTHREAD="-lpthread"
LIBCAP="-lcap"
GSOAP=""

Also, I don't understand the “grep: invalid back reference “ statement in the Start-up script, could this be causing my problem?

Thanks for any ideas dickk

[dmik]

It seems that your tool chain installation is broken so ILINK is used instead of WLINK. Do you have the gcc-wlink package installed? If so, do you have SET EMXOMFLD_LINKER=wl.exe and SET EMXOMFLD_TYPE=WLINK in your CONFIG.SYS?

[dickk]

Adding those two lines to config.sys resolved the problem with pthread, now libxml2 version 2.7.7 seems to have problems!

[Valery V. Sedletski]

did you installed libxml2-devel ? libz-devel ?

[dickk]

yes, they both are installed:
libxml2-devel 2.7.7-5
zlib-devel 1.2.5-5

[Valery V. Sedletski]

Please try do remove zlib-devel package, and install it again. It says,

weakld: cannot open library file '\@unixroot\usr\lib\z_s.a'.

(the lib is called libz_s.a actually) -- or check that e:\usr\lib\libz_s.a is present on the disk.

[dickk]

Removing and re-installing zlib-devel resulted in a different error:

Checking for pthread: found, OK.
Checking for libxml2:

neither pkg-config nor xml2-config found!

Check E:/5.0.6Netlabs/configure.log for details
#

and configure log says the same thing:

* Checking libxml2 *

neither pkg-config nor xml2-config found!

There is no libz_s.a in e:\usr\lib

This looks now, like its looking for Linux package?

[diver]

how did you install the requirements? by yum/rpm or by hand? As it really seems your env is broken.

[dickk]

requirements were installed by using yum/rpm as included in install of eCS 2.2bII. Probably the requirements as listed in Netlabs need updating as the required changes to config.sys mentioned by dmik which allows pthread to compile using wlink.exe rather than ilink.exe without errors is not mentioned. Possibly there are other needed requirements?

[Valery V. Sedletski]

did you updated the dependencies? Packages from eCS 2.2 may be old

yum update

and, is pkg-config installed?

yum install pkgconfig

[dmik]

@dickk, regarding config.sys changes, you should not have to do it manually! The command yum install gcc-wlink should have done it for you. If it haven't then you really have a broken RPM env. Please try to update as suggested by @valerius.

[dickk]

dmik:yum install gcc-wlink worked- thanks!
@valerius:yum update

I tthought I'd figured out the problem -- maybe you use the i686 version of the required packages?, so I switched to them! All went well till I did:

I give up! (yum/rpm has done me in!) Thank you both for you're help, I'm sure you have better ways to spend you're time, so I'll not bother you anymore.
@valerius: Thank you especially, for all the hard work you have put in compiling Virtualbox! It looks like you are getting close to workable version we all can use.

[diver]

as you gave up I close the ticket. I have no idea how your build env looks like, but you can be sure all builds out of the box. We all use it.
Anyway a preview should be available rather soon now.

[Valery V. Sedletski]

2dickk: If you need other arch than i386, you need to reinstall the yum/rpm environment (first delete your current \var and \usr trees, and install the bootstrap .WPI package: ​http://rpm.netlabs.org/bootstrap/rpm-yum-bootstrap-1_5-p4.wpi, then start the yum shell and follow the directions it gives)
