Hi, I can’t compile Nginx with the secure download module. It keeps complaining about a missing mhash.h file. How to I tell Nginx where to find this mhash? Do I need to install mhash or just have the sources at hand? Thanks ---

hi there are many ways to do this, in the end the gcc which is called by make just has to find mhash’s header files and the shared library. if you install the mhash and mhash-dev packages and your distribution doesn’t set it up automatically so that gcc can find it, you can still set CFLAGS to something like -I/path/to/headers and LDFLAGS to -L/path/to/shared/library before you do the configure. but in the most distribution i think you shouldn’t need to do this after installing the mhash-dev or mhash-devel package mauro ---

I’m running OSX Leopard, and I’m trying to install all that through the passenger installer. Adding the -I/path and -L/path appear as invalid options for the installer: ./configure: error: invalid option “-I/…/mhash-0.9.9.9/include” Yeah I know one day I’ll correctly learn C. ---

Here is the error message even with the env vars set: gcc -c -pipe -O -W -Wall -Wpointer-arith -Wno-unused-parameter -Wunused-function -Wunused-variable -Wunused-value -Werror -g -D\_LARGEFILE\_SOURCE -DBUILDING\_NGINX -I src/core -I src/event -I src/event/modules -I src/os/unix -I /path/pcre-8.10 -I objs -I src/http -I src/http/modules -I src/mail -o objs/addon/ngx\_http\_secure\_download/ngx\_http\_secure\_download\_module.o /path/ngx\_http\_secure\_download/ngx\_http\_secure\_download\_module.c /path/ngx\_http\_secure\_download/ngx\_http\_secure\_download\_module.c:9:19: error: mhash.h: No such file or directory We can notice that the -I/usr/local/mhash-0.9.9.9/include hasn’t been injected in the gcc command line, maybe the passenger install script overrides them or doesn’t use them. I have contacted the developer of the module and I’m waiting for his reply. ---

these are not supposed to be parameters to the configure script. they are parameters to gcc. so if you want that your make passes those to gcc you need to set those two env variables before you execute the configure like f.e.: export CFLAGS="-I/usr/local/mhash-0.9.9.9/include" export LDFLAGS="-L/usr/local/mhash-0.9.9.9/lib" or you could also try to manually edit objs/Makefile after running configure and add the two parameters like this: 3 CFLAGS = -I/usr/local/mhash-0.9.9.9/include 4 CPP = -I/usr/local/mhash-0.9.9.9/include 5 LINK = $(CC) -L/usr/local/mhash-0.9.9.9/lib you just need to make sure that gcc has the -I parameter while compilation and the -L parameter while linking ---

yes, seems that for some reason the configure which is run by passenger doesn’t take your environment variables. i have never used passenger before, but if there is some way for you to stop after the configure and then later continue with the make you could maybe try to hack the objs/Makefile inbetween. mauro ---

By compiling Nginx manually (without support for passenger), I can go a bit further, but I now hit a new problem: error: mutils/mhash\_config.h: No such file or directory When I locate the missing file I see: mhash-0.9.9.9/mhash-0.9.9/include/mutils/mhash\_config.h What is that? What’s that 0.9.9 folder doing here? Does it mean I need to add an additional -I folder? How to do that with my CLFAGS and LDFLAGS? ---

i guess the .in file is somwhere in the source of the library that you downloaded, not in the directory where the headers got installed to, right? you first should know where the headers are installed to and then make sure that gcc is getting a -I with this directory. ---

In my mhash folder I have mhash\_config.h.in not mhash\_config.h !?
