在 Mac 电脑上的Matlab安装emd工具包的时候遇到的问题。求解！！

type help function_name for more information on a specific function
Empirical Mode Decomposition
emd - computes EMD and bivariate/complex EMD with various options
emd_local - computes local EMD variation
emd_online - computes on-line EMD variation. Note that it does not truly
apply on-line: the function is only a demonstration.
emdc - fast implementation for EMD with Cauchy-like stopping criterion
(requires compilation, see make_emdc function)
emdc_fix - fast implementation for EMD with predefined number of iterations
(requires compilation, see make_emdc function)
cemdc - fast implementation for bivariate/complex EMD (first algorithm)
with Cauchy-like stopping criterion (requires compilation,
see make_emdc function)
cemdc_fix - fast implementation for bivariate/complex EMD (first algorithm)
with predefined number of iterations (requires compilation,
see make_emdc function)
cemdc2 - fast implementation for bivariate/complex EMD (second algorithm)
with Cauchy-like stopping criterion (requires compilation,
see make_emdc function)
cemdc2_fix - fast implementation for bivariate/complex EMD (second algorithm)
with predefined number of iterations (requires compilation,
see make_emdc function)
Utilities
install_emd - setup Matlab's path and compile the C codes.
uninstall_emd - revert the modifications made by install_emd and remove the
files (optional).
make_emdc - compile all C codes
emd_visu - visualization of EMD
cemd_visu - visualization of bivariate/complex EMD (automatically called
by emd_visu when the input is complex)
cenvelope - compute envelope curves for bivariate/complex EMD
cemd_disp - visualization of envelope curves and tube envelope
plot3c - plot a complex vector in 3 dimensions
plotc - plot the projection of a complex vector on a variable direction
dirstretch - directional stretching of a complex vector
hhspectrum - compute Hilbert-Huang spectrum (need the Time-Frequency Toolbox
http://tftb.nongnu.org)
toimage - transform a spectrum made of 1D functions (e.g., output of
"hhspectrum") in an 2D image
disp_hhs - display the image output of "toimage" as a Hilbert-Huang spectrum
addtag - add a tag to a graphic object (uses the Tag property as a list
of keywords or "tags")
rmtag - remove a tag from a graphic object (uses the Tag property as
a list of keywords or "tags")
hastag - test whether a graphic object has a specific tag (uses the Tag
property as a list of keywords or "tags")
findtag - find objects having a specific tag (uses the Tag property as
a list of keywords or "tags")

Warning: The compilation of the following files failed:
> In make_emdc at 48
In install_emd at 26
emdc.c
emdc_fix.c
cemdc.c
cemdc_fix.c
cemdc2.c
cemdc2_fix.c
Some errors occurred during compilation. See details above.
Installation complete. Run index_emd for a list of functions.
IMPORTANT: After running INSTALL_EMD you must run the "savepath" command to save the installation
but be careful that if you previously removed parts of the path (using e.g. the "rmpath" command)
these will be permanently removed after you run "savepath" 不好意思，第一个不对，问题是第二个。
