Hi,

I'm hoping someone can assist me. I'm trying to compile and install php-5.6.28 on a RHEL 6.7 but I'm getting this at the end:

"checking for location of ICU headers and libraries... not found

configure: error: Unable to detect ICU prefix or no failed. Please verify ICU install prefix and make sure icu-config works."

I've tried adding the EPEL repo and even tried manually downloding the "libicu-devel-4.2.1-9.5.x86_64.rpm" but I'm getting

"warning: libicu-devel-4.2.1-9.5.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 0b8f71fe: NOKEY

error: Failed dependencies:

        libicu = 4.2.1-9.5 is needed by libicu-devel-4.2.1-9.5.x86_64"

 

Thank you in advance!
