MAC OS Lazarus compiling 'Assembler was not found, switching to external asse.. lazarus / 15-macOS - Mac OS X ---------------------------------------------------------------------- Peter_laz · 2011-02-07 19:46 I am a newby at Lazarus but i have done a lot of programming under turbo pascal some years agoo. I installed Lazarus under Linux and tried to migrate a simple pascal program to MAC OS 10.6.6. I installed the files: fpcsrc-2.2.4-intel-macosx.dmg, lazarus-0.9.28.2-i386-macosx.dmg and fpc-2.2.4.intel-macosx.dmg. I copied the pascal files from Linux to Mac and tried to compile. But the result is:  Error: Assembler as not found, switching to external assembling  Fatal: There were 1 errors compiling module, stopping Question: How do I install the assembler part? ---------------------------------------------------------------------- Phil · 2011-02-07 20:03 Make sure you've installed the Xcode tools from your OS X disks. I would strongly recommend that you start with FPC 2.4.2 and the latest 0.9.29 snapshots from Daily Snapshots at the left side of this page. You're using a version of Lazarus that is about 1.5 years old. Thanks. -Phil ---------------------------------------------------------------------- Peter_laz · 2011-02-07 21:45 Thank you Phil, I found thate latest versions but I still have to install Xcode. It is not standard on my computer. Let you hear about it later on this week. ---------------------------------------------------------------------- Phil · 2011-02-07 21:48 Isn't Xcode on the Snow Leopard installation disk? It's not installed by default on a Mac since most users would have no use for it. You can also download Xcode from Apple, but it's a rather large download (about 3 Gb). The current version is 3.2.5. Thanks. -Phil
