lad to Just a quick note I thought I would drop to anybody who is having this error popup when trying to compile PHP:
[quote]/usr/libexec/elf/ld: cannot find -lltdl[/quote]
If you want to fix that error all you really need to do is go back into your source tree for libmcrypt. and execute the following commands:
cd libmcrypt-2.5.7cd libltdl./configure--enable-ltdl-installmakemake install
turns out that FreeBSD porting process doesn’t do this for you. I also am hearing word that not many if any of the automated packaging systems do this. So, hopefully I saved somebody out there a headache

You saved me a headache. Thanks. You may want to change
./configure –enable-ltld-install
to
./configure –enable-ltdl-install
Glad I could help.
Thanks for the heads up about the typo. I fixed that and also edited so those commands don’t all show up on the same line.
Next time maybe I’ll double check an entry after I post
Thanks alot! I have been struggling with this for a few hours now and finally I googled your answer. Thanks man!
Successfully compiling libmcrypt seems to solve a dependancy issue when attempting to configure/make PHP, namely:
“configure: error: mcrypt.h not found. Please reinstall libmcrypt.”
This seems to be a very common issue, so I thought it was worth mentioning. PHP compiled smoothly after I ran this.
