How to build on Mac (mainly: where to find zlib?)

[JoeStrout]

I'm trying to use NSIS to build Windows installers on my Mac. It appears to be one of the few tools out there that can do this (though I'm open to other suggestions if you have 'em).

I'm stuck on finding zlib for Win32, which it appears to require. I tried downloading the Binaries package from http://gnuwin32.sourceforge.net/packages/zlib.htm, and setting my ZLIB_W32 environment variable to point to the directory where I unzipped that, but scons still aborts with "zlib (win32) is missing!". I also tried pointing ZLIB_W32 to the zlib/bin directory, but get the same result.

I rechecked the build documentation, which doesn't have anything about this in the POSIX section, but does mention that "for Windows" I should get the zlib-1.2.7 prebuilt package linked here. So I downloaded that, unzipped it into my devtools directory, and updated my ZLIB_W32 environment variable to point to it. Then tried scons again... same result:

code:

What am I doing wrong here?

Note that I have searched this forum for "Mac" (no matches), and googled around for more detailed instructions on how to build this thing on OS X, but turned up nothing. Any tips would be very appreciated.

You could try checking config.log in the root of the nsis source tree.

It sometimes also helps to delete .sconsign.dblite, .sconf_temp and build.

There are some threads about Mac on our bug tracker, you could check those.

Hopefully someone with more POSIX experience will chime in...

[Yathosho]

The problem is known, but you don't have to build your own NSIS binaries if you're fine with v2.46. That's available on both, Homebrew and Mac Ports.

If for some reason, you have to build NSIS binaries, does this only happen when building 3.0? Would be great if this could be solved (by someone better with POSIX experience) to get the beta running on both package managers.

Edit: I also remembered posting this on Stack Overflow, but no solution has been found

[Yathosho]

For the record: I don't have any zlib-related problem when building 2.46

I'm getting the same error when compiling on an Ubuntu-based Linux distro

I believe the nightly is built on Ubuntu (drone.Io), you can see the nightly script @ http://sourceforge.net/p/nsis/code/H...unk/nightly.sh

[JasonFriday13]

Try specifing the ZLIB_W32 variable on the scons command line, if that fails use 'export ZLIB_W32="path/to/folder"' before calling scons. I have a VM setup identical to the nightly build (ubuntu 12.04 with the old cross-compiler triplet).

I'm hoping to remove the requirement for windows zlib files on linux completely by adding a wxwidgets version of zip2exe, which is the only program to use it.

I already tried that before and all I got was a different error

Before:
Please specify folder of zlib for Win32 via ZLIB_W32

After:
zlib (win32) is missing! (Mac)
zlib (posix) is missing! (Linux)

Just to be clear, which version of zlib do you use: Windows or native; source or binary? On OS X I tried both, including a mixed setup — without success. I haven't tried that on Linux, but I guess once I understand the details how to get it running on Linux, I can manage on OS X.

PS: I will give the nightly a try when I get home!

[Yathosho]

Ubuntu: I can't build it using the SCons command from the script, but this worked fine (after installing the dependencies, of course):

code:
scons ZLIB_W32=/tmp/zlib SKIPUTILS="NSIS Menu"

OS X: Still getting zlib (win32) is missing! after wgetting the same file as in nightly.sh

[JasonFriday13]

I haven't touched a single Apple product, so you are on your own, sorry.

And nobody asked you to – my questions were not Apple specific but regarding POSIX platforms in general.

Anyway, the script provided by Anders solved all my previous problems. While I'm still figuring out how to get building to work on OS X, I'm installing FreeBSD to see whether this is a general issue with BSDs.

Cool. Good idea trying FreeBSD, I didn't think of that.

[Yathosho]

I'm not much of a help here, I have problems running FreeBSD (actually GhostBSD) in VMware. Apparently, I'm not alone with this problem, but none of the advised solutions were of help.

Apart from this, I tried building NSIS on Fedora, but ended up with the same old zlib (posix) is missing! error. If anyone with more experience would like to look into this, this is what my adapted script looks like:

code:
# get zlib library

sudo dnf install scons mingw32-nsiswrapper zlib.x86_64 cppunit-devel.x86_64

wget -O /tmp/zlib.zip "https://downloads.sourceforge.net/project/libpng/zlib/1.2.8/zlib128-dll.zip"

mkdir /tmp/zlib

unzip /tmp/zlib.zip -d /tmp/zlib



# build

scons ZLIB_W32=/tmp/zlib SKIPUTILS="NSIS Menu" test dist-zip 2>&1 | tee build.log



# alternatively try zlib.x86_64 installed with dnf

scons ZLIB_W32=/usr/share/man/mann/zlib.n.gz SKIPUTILS="NSIS Menu" test dist-zip 2>&1 | tee build-alt.log

See attachments for build logs.

You need both the Windows version and the native POSIX version.

Kichik says that ZLIB_W32 should be used as a scons parameter and needs to point to the Windows version that you can download from our wiki. SCons also needs to be able to find the zlib-dev package for your platform (zlib.h and z library, see AddZLib in %NSISSource%\SCons\utils.py)

[JasonFriday13]

^^ What he said. The zlib(posix) error is fixed by installing the zlib package and it's -dev counterpart with the source headers. I installed this first before I started compiling nsis, that's probably why I never see this error.

Well, the problem then is identifying the equivalent zlib-dev package for Fedora and FreeBSD. They both have names different from the Debian packages. Fedora's DNF lists hundred of packages containing the word "zlib" and FreeBSD is a whole different story.

Anyway, I tried to localize the problems to help the OP, but I don't have too much time for this. Hopefully someone else can pick up from here.

Looking at the history for the makensis formula, I'm positive that NSIS 3.0 will be supported as soon as it goes final.

zlib + zlib-devel on Fedora?

[Yathosho]

@JoeStrout I just thought you could take a look at how Brew compiles the source, don't know why I didn't think of it earlier

https://github.com/Homebrew/homebrew...la/makensis.rb

[Yathosho]

I finally managed to build NSIS 3.0b3 on OS X!

Kickik pointed out, that zlib is required by zip2exe, for which -imho- there's no need to be compiled on non-Windows. So you can compile using the flag

code:
SKIPUTILS="zip2exe"

or even

code:
SKIPUTILS=all

.

Here's an updated formula for Homebrew, pull request is pending

I've been working on a port of zip2exe to get rid of this problem, but it still isn't finished yet. I should really finish it off before NSIS 3 exits beta.

[Yathosho]

It sure would be nice, for the sake of offering the full feature set, but I don't see it as a requirement. It's one thing to be able to compile installers on non-Windows, but I doubt there are (m)any people who need zip2exe on non-Windows.

[JasonFriday13]

Yeah, that's the main reason why it hasn't changed. But the reason I'm doing the port is to get rid of the requirement to have windows zlib files on non-windows platforms in the first place.
