make sendfirm

[robertdundee]

In the  directory ~/rockbox/utils/MTP$ I try to create sendfirm following the instructions. I write make but I get error 1. How can I fix this>

Do you have libmtp installed? The linker can't find it.

Edit:  The wiki lists the dependencies:

The sendfirm utility is used to upgrade the firmware in an MTP device. It can be found in the utils/MTP directory in the Rockbox source tree; the Linux version requires both libusb and libmtp (and their development packages) to compile and use. This utility can be used from Linux and Windows.
For Linux: to compile, just type make in the utils/MTP directory.
For Windows: make sure you have MingW installed and type make sendfirm.exe in the utils/MTP directory (or download the binary here).

Thank you. Yes, I have both libusb and libmtp installed. Im stuck on this part. Any advice is greatly appreciated

[saratoga]

Do you have the development packages too (so that would be a total of 4 packages not 2).

[robertdundee]

Yes, i do have all the packages installed in ubuntu

You probably have an old version of gcc which cares about the order when linking.
Try to edit the Makefile (at utils/MTP/Makefile) and replace this line:

Code: [Select]

gcc $(EXTRA_CFLAGS) $(CFLAGS) $(LIBS) -o $(OUTPUT) sendfirm.cby this line:

Code: [Select]

gcc $(EXTRA_CFLAGS) $(CFLAGS) -o $(OUTPUT) sendfirm.c $(LIBS)

Many thanks Pamaury !

Those are just minor warnings. If they really bother you, just add this line to the top of sendfirm.c:

Code: [Select]

#include <stdlib.h>

Thanks. When I try the make sendfirm.exe Im having the following problem>
mingw32-gcc -Wall -o sendfirm.exe sendfirm_win.c MTP_DLL.dll
make: mingw32-gcc: Command not found
make: *** [sendfirm.exe] Error 127

[pamaury]

To compile sendfirm under Windows, you need the MingGW compiler which is not super easy to install. In this case I suggest you simply use the prebuilt version: https://www.dropbox.com/s/9vwc4qdyh0c6e0p/sendfirm.exe?dl=0 (note that this link is on the wiki page...)

[robertdundee]

Thank you Pamaury. I will do that

[gordonrgw]

Thanks all,

I know this is 5 years later, but this sorted my make on Linux Mint 19.2 also..
