What is the digit for in ./bootstrap.sh -j4 ?
On the Installation Guide page of the FreeSwitch wiki, it says the following: ------------------------- You can use multiple cores for your bootstrap/config/build, by specifying it at the start, e.g.: (note this may make build errors harder to spot) ./bootstrap.sh -j4 -------------------------- I looked through the bootstrap.sh code, and it appears that the trailing digit in the above example is ignored? Or am I missing something? I was thinking/hoping it was a way to specify the maximum # of background processes that get created. At this point I assume it is just an error in the wiki.
The -j4 is a compiler flag, so it probably just passes through to the compiler without being touched by the shell script. On May 18, 2012 5:36 PM, "Tom C" <mel0torme@gmail.com> wrote:

if it's not used now, it may have been in the past - someone here that has been around for a few years may recall and probably why the wiki page says (note this may make build errors harder to spot) and it was removed because of that reason. either way, just to clarify, here's my 2cents use it with 'make' command e.g. make -j4 will use 4 cores for compiling if there is a make command in bootstrap.sh it may be passed there. configure and bootstrap are just scripts to organise things. I haven't looked inside them whether either calls 'make'. HTH Chris On 19/05/2012, at 10:27 AM, Komar, Jason wrote:

Make j works in most cases... If there are errors we would like to know about them.... As I said in the earlier reply tho, ./bootstrap.sh j ignores any numbers after the j K On 5/18/12 7:53 PM, "Chris Mylonas" <chris@opencsta.org> wrote:

use it with 'make' command e.g.
make -j4
will use 4 cores for compiling if there is a make command in bootstrap.sh it may be passed there. configure and bootstrap are just scripts to organise things. I haven't looked inside them whether either calls 'make'.

The digit on the bootstrap doesn¹t do anything, its ignored... The j says parallelize the bootstrap... This will spawn off a pile of background shell scripts to make the bootstrap go faster. K On 5/18/12 6:36 PM, "Tom C" <mel0torme@gmail.com> wrote:
