empty/missing DT_Hash

[tf]

Hey guys,

I tried to build newlisp for android for the newest nexus 7. when I

ran it I got "cannot link executable: empty/missing DT_Hash in

"./newlisp" (built with --hash-style=gnu?) Would somebody please

point me in the right direction?

Thanks!

The Android dynamic linker doesn't support gnu-style hash tables, try building with --hash-style=sysv or --hash-style=both

Thank you very much.  Pardon my ignorance, though--where do I specify the hash style? in a file?  ./ndk-build --hash-style=sysv doesn't work... how do I tell the ndk to use a particular hash style?

[David Turner]

It's a linker flag (see man ld) :-)

ndk-build uses the NDK toolchain which defaults to '--hash-style=sysv' anyway, so this problem shouldn't exist unless you use prebuilt libraries or another build system / toolchain.

In both cases, try regenerating the non-ndk-build  binaries after adding --hash-style=sysv to your LDFLAGS.

Hope this helps.

Hi Digit,

I have the same problem event if I add the following line in my Android.mk.

LOCAL_LDFLAGS += -Wl,--hash-style=both

the output when  I add the above option:

WARNING: linker: pmdump: unused DT entry: type 0x6ffffef5 arg 0x3b0

WARNING: linker: pmdump: unused DT entry: type 0x6ffffffe arg 0x458

WARNING: linker: pmdump: unused DT entry: type 0x6fffffff arg 0x2

CANNOT LINK EXECUTABLE: cannot locate symbol "__register_atfork" referenced by "pmdump"...

My program named pmdump.

If I remove the above option from my Android.mk, the output:

WARNING: linker: pmdump: unused DT entry: type 0x6ffffef5 arg 0x3b0

WARNING: linker: pmdump: unused DT entry: type 0x6ffffffe arg 0x400

WARNING: linker: pmdump: unused DT entry: type 0x6fffffff arg 0x2

CANNOT LINK EXECUTABLE: empty/missing DT_HASH in "pmdump" (built with --hash-style=gnu?)

I am using the AOSP 6.0 source code and environment to build my program, and the final executable work fine on my device which runs Android 6.0.

And it doesn't work on my another device which runs Android5.1.

I tried to using the AOSP 5.1 source code and environment to build my program without the ld option mentioned above, and the final executable work fine on my device which

runs Android 5.1 as well as my device runs Android 6.0.

It seems like that the difference build process between Android 6.0 and Android 5.1 cause the issue, I want to build my executable and runs well both in devices runs 6.0 and 5.1.

Any suggestion will be appreciated.

Thanks

You can't do that. If you target 6.0, 6.0 is the minimal platform your app will work on.
