Hello everyone, I installed h8300 toolchains in eCos 3.0 and tried to run application using Akizuki H8/3068 Template on Akizuki Board. But I was encountered by application's Make-error and in a deadlock predicament. Would you please help me and rescue me out ?
I used next sources. binutils-2.19.1.tar.bz2 gcc-4.4.0.tar.bz2 newlib-1.17.0.tar.gz As I said, I succeeded to install h8300 toolchains in /gnutools directory and succeeded to install RedBoot in Akizuki Board. Next I decided to run eCos-bundled nc_test_slave.c and tried to build libtarget.a. In order to build libtarget.a, I selected Akizuki H8/3068 Template and "net" package. Here, I've met a serious error problem. /opt/ecos/ecos-3.0/packages/language/c/libm/v3_0/src/mathincl/fdlibm.h:78:3: error: #error IEEE-style 64-bit doubles are required to use the math library Here're extracts from original fdlibm.h. --- // SANITY CHECKS // Just check that we support IEEE-style 64-bit doubles. If not, this // math library will not work // This check will go away when support for single-precision alternatives are // provided #if DBL_MAX_EXP != 1024 # error IEEE-style 64-bit doubles are required to use the math library #endif // if DBL_MAX_EXP == 1024 --- Tell the truth I didn't understand but when I searched DBL_MAX_EXP in .c and .h files couldn't find it, so I escaped by next simplistic evasion. --- #define DBL_MAX_EXP 1024 #if DBL_MAX_EXP != 1024 # error IEEE-style 64-bit doubles are required to use the math library #endif // if DBL_MAX_EXP == 1024 --- I inserted #define DBL_MAX_EXP 1024 !! I could see your scolding faces but I needed to make it,so let me continue my story. Anyway I succeeded to make libtarget.a,so next I continued to make application. And I've run across next linking error. $ make h8300-elf-gcc -c -o nc_test_slave.o -mh -mint32 -g -Wall -I/home/link/aki-net-0717/untitled_install/include -ffunction-s ections -fdata-sections nc_test_slave.c nc_test_slave.c: In function 'do_udp_test': nc_test_slave.c:215: warning: format '%x' expects type 'unsigned int', but argument 2 has type 'long int' nc_test_slave.c:215: warning: format '%x' expects type 'unsigned int', but argument 3 has type 'long int' nc_test_slave.c: In function 'do_tcp_test': nc_test_slave.c:391: warning: format '%x' expects type 'unsigned int', but argument 2 has type 'long int' nc_test_slave.c:391: warning: format '%x' expects type 'unsigned int', but argument 3 has type 'long int' h8300-elf-gcc -nostartfiles -L/home/link/aki-net-0717/untitled_install/lib -Wl,--gc-sections -Wl,--Map -Wl,nc_test_slave .map -o nc_test_slave nc_test_slave.o -Ttarget.ld -nostdlib /gnutools/lib/gcc/h8300-elf/4.4.0/../../../../h8300-elf/bin/ld: skipping incompatible /gnutools/lib/gcc/h8300-elf/4.4.0/ libgcc.a when searching for libgcc.a /gnutools/lib/gcc/h8300-elf/4.4.0/../../../../h8300-elf/bin/ld: cannot find libgcc.a collect2: ld returned 1 exit status make: *** [nc_test_slave] Error 1 I confirmed there is libgcc.a in /gnutools/lib/gcc/h8300-elf/4.4.0/. I do not know it is directly related to my botched evasion. Please show me the correct way. By the way,please let me use an assumed name.Recently I discovered my original name is used by spams. May be punished the spam builders !
